SciShow asked on Twitter and the Community tab if people had eclipse questions so I stole them and made a video!!! Video edited by Milo! miloportfolio.carrd.co/
It's actually a bit better than on land, because your boat can move along the path of totality and thus get a few more seconds of the gorgeous view than you'd otherwise have access to. Over land the only good way to do that is in a plane, because roads only rarely point the right way and you're likely to crash as your driver gets distracted.
@@whopperlover1772 napkin math says not quite negligible, but close - the eclipse moves at 1,500 mph, so going 15mph would give you 1% more viewing time
@@bakedbeanfanclub that’s quite literally negligible. For a 4 minute totality, which is already super long, that would give you 2.4 seconds more totality.
LOL, just saw a cop at the corner store in his car and I asked, "You ready for the eclipse?!" and he smiled and gave me a thumb's up. (We're in the path of totality, unlike in 2017.)
We got an amazing view in 2017, and are traveling to watch this one. Until you've seen one, you just can't understand how incredible it is to experience. Hank is dead on-air is WAAAY cooler than you think.
I saw the 2017 eclipse in my front yard in Oregon. It was one of the neatest things ive ever seen. The world went quiet. All birds, all insects all silenced. Then it got dark. And everything got cooler. It was terrific.
Same here in Nashville! That was my senior year of high school and they let us have that day off. We went to the Football field and it was perfect. Not a cloud in the sky. One of the most incredible experiences I've ever had. So sad I have to work on the day of the eclipse this year :((((( I'll be 44 years old when the next one comes around
I had seen partial eclipses before, so I figured it was all hype or "cool but not THAT cool". After seeing totality in 2017 I now understand why old stories of predicting eclipses were viewed as religious events. It was amazing.
All of this, exact same exp, exact same state I so wish i cud see totality this yr, but i cant afford to travel rn even tho ive got the time and its actually gonna pass thru the state i now live in; just the other end of this less than an oregon sized state Its an unimaginably cool experience if youve not seen it; and indescribably cool if youve seen jt
Same. I didn't even have to travel to see it, but I went a little further south to be in it for a few minutes longer. Wound up in a random field on the side of the road with 3 other cars. Absolutely awe-inspiring. What I found coolest, besides the eclipse itself, was that we were in the middle of what I can only describe as an all-encompassing sunset. You could see the hills around us tinted pink in all directions with us dark in the middle. I'll never forget it.
You can't make homemade glasses, but you can make a homemade pinhole camera to project the eclipse on a surface of your choosing, assuming you can make it sufficiently dark around the projection area
During a partial eclipse I just used my hands to make a pinhole, shadow puppet style. It is actually pretty cool to see the projection change into a crescent shape as you make the hole small enough.
I did this with the last eclipse (that I was in a place that I could observe it) with two paper plates! They were the sturdy white fibrous kind and they worked great! :)
The reason it still hurts your eyes as much as it would if there wasn't a partial eclipse is because your eyes are adjusting to the visible light and not to the UV light. So your eyes end up bringing in a ton more UV light by comparison. Also, don't go buying up all of the welding glass, it's cheaper to get the disposable solar eclipse glasses and you can reuse them if you just fold them up and put them in a safe place
Is the whole of the eclipse dangerous in that regard or is it just the transition between partial and total eclipse? I think I've heard that you can actually look at a solar eclipse without glasses if all you can see is the sun's corona, i.e. you're in the path of totally and the sun is fully covered up by the moon
@@rfldss89The only time it’s not dangerous is for the few minutes of totality when you have to take off your eclipse glasses or you won’t see anything.
@@kilhapuritybold ok, yes, but still, unless you're gonna be using it on the regular, needlessly driving up prices for welding PPE is not healthy for the working class budget.
I did learn the answer to the danger question several years ago, but totally agreed on how poorly it's always explained because it always drove me nuts when I was younger. The sun is *clearly*, *demonstrably* less bright during a solar eclipse, why is everyone acting like it's suddenly so much more dangerous?! And when someone *finally* put it to me like "No, it's exactly as dangerous as looking at hte sun always is, it's just physically EASIER to do during the eclipse." And, that made perfect sense, and I then I was mad that no one said it like that before, lol. I also enjoyed that description of lagrange points.
But mostly because we all really want to look at the sun. It is not actually easier to look at it, even at 1% it is still too strong to look directly at it. So it is more likely that the damage is due to using fake eclipse glasses or sunglasses.
I experienced the 2008 total eclipse in China. It was a normal school day... until it pretty suddenly wasn't. We ran outside into the weird day-night, eerily absent the sound of birds. It was smoggy, so our viewing glasses were useless, but the experience of just being there, surrounded by classmates, teachers, and darkness, was more than remarkable. Edit: corrected year
I think the thing that surprised me most in the 2017 eclipse (I camped out in Southern Idaho for it), was how cold it got so suddenly. Like it sounds so obvious that it gets colder without the sun, but what I didn't realize was how much of that heat is actively falling on you, not just sitting in the atmosphere around you. Less than a minute after totality, the temperature drops *precipitously*, like probably multiples of 10s of degrees (it felt like it dropped 15-25 F for us), and it's the thing that sits with me most to this day.
I love that this is earth's fascinating quirk. If we were from any other planet, discovering earth, it would be on the list of obscure science facts about earth. _"Jupiter's day is only 10 hours long, which is the shortest in that system. Pretty neat"_ _"Earth's distance from the sun and its moon align just right for a thing called »total lunar eclipses« to happen"_
So much so, that if we ever found ourselves in a galactic community and needed a flag or logo for planet Earth, a diagram of a total eclipse would be unique enough for us to use without ambiguity.
I love that each person sees the corona differently because of their eyes being slightly different. It's like the sun is saying something to you specifically. It's so cool!
Unfortunately I think large hills are hard to come by for most of the path of totality. I'll be on a small hill surrounded by woods, hopefully I'll still be able to catch that!
@@IndyJay53 as long as your view isn't blocked by the woods, I think you should be OK. I've only experienced this once by accident (in 1999) but I recommend just looking down at the view towards the west (by southwest) in the last few seconds leading up to totality. The shadow will going 720 mph across the ground. Let me know how it goes! For comparison, if I remember correctly, I think this was my view at the time so not much of a hill either: www.google.com/maps/@49.4734016,5.2214433,3a,75y,226.88h,89.41t/data=!3m7!1e1!3m5!1s3oT92gAf6cThE58gwG7jDg!2e0!6shttps:%2F%2Fstreetviewpixels-pa.googleapis.com%2Fv1%2Fthumbnail%3Fpanoid%3D3oT92gAf6cThE58gwG7jDg%26cb_client%3Dmaps_sv.tactile.gps%26w%3D203%26h%3D100%26yaw%3D282.07462%26pitch%3D0%26thumbfov%3D100!7i16384!8i8192?entry=ttu
Am from Ohio, can confirm is very flat. You’d probably have to go over to Maine in order to get that effect, or maybe somewhere between Buffalo, NY and Erie, PA where you can overlook Lake Erie
I personally think the coolest part of an eclipse is how the outside shadows get otherworldly sharp. Really cool, so cool I wish I lived closer to where the eclips is happening.
HANK. I witnessed the 2017 eclipse in totality very much on a whim thanks to my science obsessed brother. It was miraculous. There are no words to properly explain the experience. These past few months I've been SOOOOO tempted to make the drive to the zone of totality, but everyone around me talked me out of making the trip because A) I'm about 6 hours away and B) I teach high school and it's testing season, so absences are highly discouraged. Your enthusiasm is giving me the most intense FOMO. I'm tempted to channel my rebellious teenaged self and just friggin do it. Screw logic and responsibility! I want to witness magic again!!
Do it. This opportunity comes just once. Well, this is my third. I can't really remember the first, making pinhole veiwers in grade school, no glasses. 2017 was amazing when the light shining down through the trees cast little dancing crescents all over the ground. Don't miss the magic. Wish you could take your students. ❤
Do it!! I'm a teacher, too! Your students won't remember those terrible tests, and in a couple of years, neither will your school district. If you play hookie and then come back with your stories about the experience, your students will absolutely remember your joy. DO IT.
I experienced just over 2 minutes of totality in the Great American Eclipse. I understood the science of what was happening. I'd seen pictures, read articles, watched videos.... None of that prepared me for the absolute MAGIC! No one can really describe it... it's very moving.... one must experience for oneself. It's entirely understandable why people in olden times were shocked and scared! OF course, you see the difference, but it doesn't just get darker... all the reds and yellows fade, and the world turns a bit blue, and it gets cooler. The sounds change, too.... birds go quiet... insects start up... Yes... in just those few minutes of totality or near totality... Stay safe, don't look without the CORRECT glasses (We got some you can comfortably watch TV through.... YIKES!!!!! We replaced those!) I think it was the most magical moment of my life! (other than the birth of my daughter) ... It's worth taking the day off... pulling the kids from school.... driving a good distance! I REALLY HOPE it's not cloudy in Cleveland!
I am extremely sad right now. So my dad lived in Tennessee and was right in the path of totality in 2017. He's never been somebody to gush over anything but he made it a point to tell me that it was the most magical and life-changing experience of his life. After that phone call, I googled when the next one was going to be, and I saw that my house is going to have three to four minutes of totality for this eclipse. I couldn't believe it, I was so excited! But... I'll never get the chance to tell him that he was right because he passed away last year. So I feel insanely connected to him by what's about to happen on Monday. I just looked it up... Local weather people are predicting zero visibility. Like no shot of actually seeing the eclipse. I'm standing outside right now in the most beautiful day imaginable and I have to continue into the weekend knowing that I'm not going to get to see it.
It will still be amazing because it will go black unlike it does in clear places. If you can get to a hill, do that so you can watch it go black in a line over the earth.
01:34 - I think Hank got this backwards. When the Earth/Moon system is further away from the Sun the apparent size of the Sun is *smaller*, and thus the Moon is more likely (it has an elliptical orbit around the Earth as well, so its apparent size as seen from the Earth also varies) to be able to fully cover the Sun. The Earth(/Moon) is closest to the Sun in December, furthest away in July. So Total Solar Eclipses will happen in Northern Hemisphere Summer more than in NH Winter. To have an eclipse you need the Sun to be visible, i.e. it to be daytime, and there's more of that in local Summer.
To be fair, he later states this around the correct way, so just a brainfart in the moment I think. As for the perma-eclipse, it'd be a LOT more than just being mean to one guy. It'd really do a number on life on Earth in the shadowed region.
@@AthAthanasius It really depends on whether we want the perma eclipse to be static relative to the planets surface - if we did, it'd have to be tidally locked and that has a whole lot more effects than a permanent eclipse would. If the planet was still rotating, we'd just have a big shadow sweeping across part of the planet and not really doing much harm
@@AthAthanasius He got it backward the second time around, too, saying that the Earth is closest to the sun during the Northern Hemisphere summer, which isn't the case, and if it were it would cause fewer eclipses in the Northern Hemisphere.
I love how Humankind went from being abjectly terrified of a solar eclipse, to exhibiting unbridled joy. I always love it when people clap and cheer for Nature! So you're a total solar eclipse virgin! I can't wait to hear your thoughts and impressions of it and, of course, if you clapped and cheered!
From my understanding it varied a bit from culture to culture. Plenty of ancient civilizations had a good enough understanding of the movement of the moon through the sky that they understood that an eclipse was just the moon passing in front of the sun. In a world with no light pollution and few accurate maps, the sky was the often the best way to navigate.
My family and I live in Ellettsville Indiana so we’re prepped to just stay in over the weekend see the eclipse from our home, while we let all the travelers go through town. It’s exciting for me to experience
Yeah, my area is expecting 1.5x as many visitors as people who live here. It's gonna be PACKED!! Still wondering where an extra million people are gonna fit.
Concerning the constant eclipse and the stability of the Lagrange points: some of the points are just like Hank said - unstable. But there are stable Lagrange points, namely the L4 and L5 which lead or trail the body by 60deg in orbit. They are called Trojans and they can get pretty big. The largest one being 624 Hektor which is an approximately 250km diameter Trojan around Jupiter's L4 point. The Earth has Trojans too, albeit much smaller. However as far as an eclipse is concerned the 60deg offset would mean they never come into the line of sight between the sun and the orbiting body (like Earth), and thus they would never produce an eclipse. As for the permanent eclipse, it would be possible. If the planet was tidally locked to its parent star (not the case for any planet in our solar system, but is possible) and had a moon on a distant orbit, orbiting with the same speed as the planet rotates, it would cast a permanent eclipse over some part of the planet. If it could be total however, idk. Would need to do some math. Maybe Scott Manley would know. Edit: Scott Manley: "I have not been able to come up with a stable system where a spot on a planet is always eclipsed."
I guess that a tidally locked moon/planet system that was on a perfect flat plane with their sun would have a eclipse every rotation. Maybe it would me more likely for double planets?
4:44 A quick addition that I don't think gets talked about enough: the reason you get told this during an eclipse even though it's just as dangerous to stare at the sun any other time is that the dangerous thing is to *stare* at the sun. If you glance past the sun, if you just have the sun in your field of view for a second, that's not a problem, your eyes can deal with that. I feel like people often don't wanna talk about this because it feels like endorsing staring at the sun, but not saying that it's specifically staring that's the problem confuses people like the question asker who do see the sun briefly every day and don't perceive any sense of danger from that. The reason it's not dangerous on a typical day is that if you're not really motivated to stare directly at the sun, your "ow my eyes hurt" instincts will tell you to stop staring way before you get eye damage from staring at the sun. But when there's an eclipse, people *are* really motivated to stare directly at the sun.
if you don't have glasses you can use a colander (or anything else with small holes) to see the eclipse in the shadows! The circular shadows will become mini eclipses. It's very cool looking and I recommend looking at the cool shadows even if you do have solar glasses
This will be my third total solar eclipse. First in my back yard when I was 7-8. Dad made us glass viewers by smoking the glass with a candle. Second on in Toronto in the ?early 90’s using a pinhole device. On the 8th I’ll be in a field with my daughter and grandkids, special eclipse viewing glasses, in my southeastern Ontario town. Since I’m 70, it’s likely my last, but I’ll be happy I shared the wonder of the solar system with another generation! 🇨🇦🖖🏻🇨🇦
Great video, Hank! I've been basically watching only eclipse-related videos for the last few days and I still learned a few things! This will be my first total eclipse as well (hopefully not my last) and I'll only have to drive an hour south to be in the path of totality. I've been waiting for this for nearly thirty years. On may 10th 1994, I was 8 years old, and my entire school was taken outside to view an eclipse. I thought it was total at the time but later learned it was only about 85% (and was in fact not total anywhere). They mentioned to us the next one in our area would be in 30 years, which of course is an insane amount of time when you are 8, but I've been looking forward to April 8, 2024 ever since. I also look forward to your post-eclipse video!
Beginning my drive from Washington State to Indianapolis tomorrow. I know flying would be cheaper, but road trips are fun! Very excited. Maybe see you there Hank!
I would guess that watching the earth, you could see a little shadow travel across it, over the course of several hours. relative to the size of the earth, the shadow would be very small, but otherwise it would be similar to a lunar eclipse as viewed from earth, nothing will really change on the moon since it's not a significant amount of light that's prevented from being bounced back.
I guess on the other hand, a LUNAR eclipse would be pretty intense from the moon. The earth is bigger than the moon (citation needed) so it'd block out the sun even more completely than our solar eclipses here on earth
@@aaaaaa-ts3rwyeah exactly! the entire moon would be eclipsed too, there wouldn't be a specific area you would have to be in to get a total eclipse. also would last quite a bit longer
There are pictures of eclipses seen from the International Space Station, and there's just this big round shadow on Earth. Should be something like that.
Not quite the same... Esp bcuz the two of us cant see it this yr despite bein so close to it; just lack of funds to travel despite the time But me and my soon to be husband (he/they) actually kinda watched the last eclipse in 2017 together We didnt know each other then, but the eclipse went over both the cities we live in, despite bein halfway across the continent from each other; so we both were able to watch it together He watched it with their late husband (he); who was an awesome man and i loved havin him as my metamour for the short time i did before cancer unfairly took him four yrs ago I had watched the eclipse with a roommate (he) and his family who had taken me in, a complete stranger, less than a yr before; and who also introduced me to an awesome little community called nerdfighters. A community that has made me grow to love this sorta stuff even moreso; and to enthusiastically and unabashedly experience such things without worry about if it makes me weird or nerdy or any other thing deemed wrong by so many
Great explanations! Quick correction on one point: the northern hemisphere's summer currently aligns with the part of the Earth's orbit when it's further from the Sun. That makes the Sun appear smaller from our viewpoint and therefore easier to block. The thing you want closer to the Earth is the Moon. Its orbit is also elliptical, and when it's closer, it appears bigger, meaning it's better able to block the Sun. Thanks for the vid Hank! Happy Eclipse!
pro tip if u don't have glasses you can see the shape of the sun by poking a small circular hole in a paper plate or something. It will cast a shadow in the shape of the partial eclipse.
13:30 I attended the total eclipse crossing Cornwall in 1999. Totally cloudy. The weirdest thing. You can see the horizon fully lit up and watch the shadow of the moon on the clouds above. Utterly surreal experience. Very different from the 2017 eclipse in Tennessee which was clear. Looking forward to this one, the weather is looking very promising for us here in Eastern Canada.
@@Anna-Bin my area most schools cancel classes because they don’t want to be responsible for keeping kids from damaging their eyes. (Average class size of 32 students is way too many kids for a single teacher to supervise when some of them certainly are prone to self-destruction)
Europe 1999 checking in. It was cloudy so we chased the bastard trying to find a gap in the clouds. Found a chink in the armour and pulled over, shit got real, animals all went quiet then started acting bizarre, making weird calls. Super dark and spooky, turns out we'd driven accidentally into Germany where we saw it, from France. I'm not sure how much of the weird phenomena can be attributed to that fact.
I work at a major international airport near the path of totality In the last 4 days, I have seen customers from every state except weirdly Hawaii; every European country in the European Union,Schengen, or NATO; every Canadian province save PEI- well long story short people aren’t just driving to the strip of totality they are coming in from around the world. I have a likely untrue and hard to prove theory that this is most widely observed anything (Coronation, football game, tv show, fireworks show, rodeo, parade whatever) in all human history.
It's crazy to me that I'm 26 and I saw a Total Solar Eclipse before Hank Green. What stopped you in 2017? It was cloudy where I was for much of the eclipse, but it was still an exceptional experience. The mere fact that it goes from being like midday (depending on time obviously) to being like midnight is incredible. Being able to experience that shift in minutes is a profound experience. Everyone should experience a Total Solar Eclipse at least once in their lives, and it depresses me to see people who have the ability to go to one and choose not to. Even if you'll see like 98% where you are, that is ridiculously different from totality. Totality was the closest I've had to a truly spiritual experience. We happen to live on a planet where our star is almost exactly 400 times larger and almost exactly 400 times farther away from our moon and it crosses behind it sometimes. That is truly exceptional. Please seek out any eclipse you have the opportunity to go to. Even Annular Eclipses are very cool (my first one was in October).
I saw totality in 2017. Seeing totality is one of the very few things that not only lives up to the hype but far exceeds. It really is life changing. The most unbelievable, awe-inspiring, beautiful, spectacular thing you will ever witness. Once you see it you “get it” and realize why people will do ANYTHING to view it again.
Additional reason looking at an eclipse is MORE dangerous: being darker out, your pupils are more likely to be dilated and letting in more light, exposing your eyes to more photons in that small portion of your retina. It's like increasing the size of the magnifying glass you're using to burn something.
Several years back we were in the path of totality. 15 people came to stay at our small house for it. It was amaizing the hype is real. Heads up, the wave of darkness happens fast.
Hank, I'm genuinely SHOCKED that you didn't travel to see the 2017 eclipse. I expect it to be in my top ten experiences until the day I die. I hope you get great weather tomorrow!
Dating my self here, but I was in the 8th grade when I saw the total eclipse in 1979. It is absolutely one of the coolest, but also an eerie phenomenon. I remember asking my mom if I could stay home from school for 2 reasons. One was that I wanted to experience the eclipse without all the other kids in my class around. The other was I didn't trust my 8th grade science teacher. He had told us we were going to go outside and look at it as a class. He had done other questionable experiments,, where we had minor accidents/injuries so it worried me. (I became a teacher BTW) It went dark, like a really bright moonlit night. All the animals went silent, no chirping birds, barking dogs, etc, extremely cool, but eerie. I've also seen several partial eclipses. If you do not have eclipse glasses, you can still watch the movement of the moon over the sun with 2 index cards. It's not as amazing as looking directly at it. To use the index cards: poke a small hole in one index card with a pin or toothpick. Stand with your back to the sun. Hold the card with hole so the sun is shiny through the hole. Put the other card behind it so sunlight goes through the hole and onto the second card. Adjust the space between them so the bright sun spot is visible. You can watch as the moon slowly obscures the sun. Like I said, it's not as magnificent, but if you don't have eclipse glasses it's possible to watch the event. It works for partial eclipse as well.
wow how did i not connect Helium with _Helios_ before??? thanks for teaching me something new today, Hank!!! (hope your recovery from the you-know-what is going well)
@@jajssblueOur moon is unusually large relative to the size of the Earth which might have even contributed to the evolution of life in various ways, such as protecting us from asteroid impacts.
Edit: The L1 (and L2) point, which is the Lagrange point you’re talking about, is actually passively stable on two axes, but not the third. It is not a maximum, but a saddle point. There is a sort of plane that is described by a normal vector pointing from L1 to Earth. You are stable on this plane, but if you move towards or away from Earth, you are no longer getting pushed back onto the point. This is how JWST orbits the L2 point: it is not centered on the point, but lies offset in the plane such that it orbits around L2 on this plane, getting pushed back towards the center as if there is a gravitational body there. It only has to forcefully keep itself located there by thrusting towards or away from Earth (assuming two-body physics). /Edit A more plausible solution (assuming the Earth wouldn’t burn up in the sun or the moon wouldn’t be so large the Earth/moon system became a binary planet system) could be if the moon’s orbital period was the same as Earth’s, it could perpetually cast its shadow. A lot would be very different if that were the case. We would probably need the sun to be a lot cooler so that Earth could be a bit closer, then have the moon be larger so it could be farther away but maintain the size ratio. These two changes would speed up the Earth snd slow down the moon. Anyway, the path is a very boring one where everything is nearly identical except the altitudes such that the periods of the moon and Earth are equal…
Hey Hank, I think you had it the wrong way round when you said that the Earth-Moon system being further away means fewer eclipses. Surely the sun would then appear relatively smaller, so it would be easier for the moon to fully obscure it? PS love your content and infectious enthusiasm!
If you're at 90+% occlusion, then it won't get that dark, but the color of the world definitely changes noticeably. Calling it dusk doesn't do it justice. It's more like being in an old movie. Also, shadows get super weird. If you look at the shadow of a tree, it'll look like a bunch of circles piled in each other. It isn't as weird as the eclipse proper, but it's still an experience worth checking out.
I live in the DFW area and i'm going with some friends to a spot that will be in the center of the path. looking at over 4 minutes of time. Super stoked. Until i've been watching the weather forecasts that are all saying almost all of texas will have cloud cover on Monday 😭 hoping for some breaks in the cloud around the time. also, we have a plan to drive this north south highway looking for a break. fingers crossed.
I just looked it up and the weather channel is showing everything from Texas to Southern Indiana being under heavy cloud cover, there are going to be a lot of disappointed people I think.
Hope you get good conditions with your solar eclipse dude, they are nuts. I recommend it near somewhere with a lot of wildlife, like a wood or park, somewhere with a lot of trees and birds.
@@sanachantoIt's true, like shadows at twilight or when there's a full moon. I was more thinking about the animals' sounds, they go quiet but then get confused and start making weird noises. Maybe it's the nocturnal ones waking up haha idk
As of right now the weather channel is predicting extremely cloudy over most of the path of totality with clear bits over western Indiana and north west Ohio. Also pretty good perdition for western and north eastern New York. Unfortunately everything from Texas to southern Indiana is supposed to be heavy clouds, as is central New York and Most of Maine. Things can change but right now its not looking great for most of the US.
My wife and I were going to go to Dallas to see it but given the forecast we decided to go to my Aunt and uncle's house in rural Illinois, which is directly in the path of totality and is supposed to be much more clear
I'm going to be heading south to central IL around Effingham and it's supposed to only be about 25% cloudy. Hopefully I-57 isn't totally jammed all day by Chicagoans doing the same.
Where do you see this on the Weather Channel? Planning on going upstate New York but weather is still a concern, need to figure out where will be the best to watch it.
I do wanna pt out; even if things are cloudy, there is still a huge exp to seein the eclipse. Someone in the comments even mentioned seein the 2016 eclipse in China and it bein still amazin even tho the smog and clouds made it impossible to see the sun eclipsed Its still amazin to experience how much colder and more quiet the world becomes when night dawns in the afternoon
The last total solar eclipse we saw in southern Ontario was when I was in grade 3 almost 30 years ago. My son is almost the same age I was when I saw it. Just so cool.
I saw the total eclipse yesterday parked on the side of a tiny road next to a cemetery along with my family and four other cars of people. There was patchy cloud, but enough that we could watch the sun get smaller and smaller; it was covered at the moment when totality began, but the clouds got just thin enough to see the corona _just_ before totality finished. It was freezing. It was amazing. The solar lights in the cemetery decorations came on, and the streetlights, and we could see high clouds still lit up like day even though it was dark for us.
"i think that you can visualize what i'm talking about" - i don't have a mind's eye hank, i certainly cannot visualize what you're talking about. but i appreciate you trying!
I tried to see the 2017 eclipse in St Joseph, Missouri, but got blocked by clouds. Managed to drive around for a while and find a thin spot in the clouds, as totality hit, getting just a brief glimpse of the corona through the haze - a blurry ring with a couple distinctive spikes I later recognized in other people's photos. Unfortunate, but it was still an impressive experience - the 360 degree sunset, the pale eerie light and distorted colors, temperature drop and breeze, and animal behaviors were still very evident, and surreal. I'm doing my damnedest not to miss this one. Traffic was also very impressive... Especially in an RV. Be careful out there.
I am overwhelmingly excited about this being a possibly huge moment in the history of solar physics! Were the solar probes purposefully sent there to be in the right place at the right time specifically with this eclipse in mind?
how did i get here 55 seconds edit: i apologise for not using this rare opportunity to say something more original edit2: last time i was this early the fuckin uhhh moon blocked ou the sun over the us. thats topical
Did the sun gods specifically target Johns house for this eclipse? because it looks like it tracks directly onto John's house just so you can go visit it and do cool science.
I found a good analogy to why looking at the sun during an eclipse is more dangerous. It's like not wearing sunscreen when it's either cold or slightly overcast. We associate sunburn with hot summer and bright sun so if the air is keeping your skin relatively cold or if you don't have that sensation of the sun beating down on you you're not going to think to slather yourself in sun block. A lot of people get sunburned if go skiing and don't know you need to put sunscreen on
Hank i love your channel but ,your description of how the eclipse happens using your hands was like watching an Italian mom yelling at her kids. An orange and a marble might have worked better....lol
I'm so hyped to see the eclipse! A total solar eclipse was one of those things I thought I'd never experience because they're so rare in any given spot, but it turned out that both the one in 2017 and this coming eclipse pass pretty dang close to where I live. So now in a few days I'm going to be seeing my second solar eclipse!
Hey thanks for the warning. Coworkers are watching the eclipse today, but today I wasn't scheduled to work, so I didn't go in. I didn't plan on getting my own eclipse glasses. I thought about using sunglasses, but as you stated, I do not want to burn my retinas for the entirety of my natural life. Guess I'm gonna miss out, oh well. Enjoy safely everyone else!
I've always wondered if staring at the eclipse was worse than staring at the regular sun, but I've never been able to find any answer's so thank you for that.
Some animals do act fairly weird during an eclipse, there is a actually a study of it happening during this one for the first time in a few decades. Anton Petrov has a great video about it!
I saw a tweet replying to someone asking what the hype for the solar eclipse was, they said if interstellar tourism were a thing we'd have aliens coming to earth by the shipload because of how unique eclipses are. It's such a crazy coincidence that the distances and sizes are so perfect that this can happen.
I watched the Aug 2017 eclipse from the beach at Road End in Lincoln City, Oregon. The eclipse was fantastic, plus if you looked the other direction over the ocean there was a "Fog Bow"
Looking forward to this one! My husband and I traveled to western Missouri for the 2017 eclipse, and it was such an amazing experience! This time we're gathering with family and friends at an AirBnB that I booked last year in south/central Indiana. Hoping for relatively clear skies. When my father was alive, astronomy was a huge passion/hobby of his, and in his retirement he had a relatively fancy telescope (for an amateur) that he had a sun filter for. My sister now has it. We borrowed it for the 2017 eclipse, and she's bringing it to our gathering for this one, too. Yes, we have our eclipse glasses, too.
Back in 2017 we drove to a country road going through a corn field in rural Missouri. We got a total eclipse and it was a totally awesome experience. It was eerie the birds started singing, the cicada got loud it felt like the evening and the quality of light was totally odd. i'd recommend it.
From my experience, cows lay down and try to go to sleep during a solar eclipse. Afterwarda they just get up and continue eating grass like nothing happened
seeing a total solar eclipse in the middle of the ocean sounds like it would be a really transcendental experience
And terrifying, like the world really was going to end.
It's actually a bit better than on land, because your boat can move along the path of totality and thus get a few more seconds of the gorgeous view than you'd otherwise have access to. Over land the only good way to do that is in a plane, because roads only rarely point the right way and you're likely to crash as your driver gets distracted.
@@ThePCguy17the speed of a boat would be negligible buddy
@@whopperlover1772 napkin math says not quite negligible, but close - the eclipse moves at 1,500 mph, so going 15mph would give you 1% more viewing time
@@bakedbeanfanclub that’s quite literally negligible. For a 4 minute totality, which is already super long, that would give you 2.4 seconds more totality.
the amount of priority/importance sci fi and fantasy give eclipses to their plot is a testament to how ABSOLUTELY AWESOME ECLIPSES ARE OHMYGOD
LOL, just saw a cop at the corner store in his car and I asked, "You ready for the eclipse?!" and he smiled and gave me a thumb's up. (We're in the path of totality, unlike in 2017.)
It's the perfect time to invade the Fire Nation!
@akpsyche1299 haha I came here to say the same thing
We got an amazing view in 2017, and are traveling to watch this one. Until you've seen one, you just can't understand how incredible it is to experience. Hank is dead on-air is WAAAY cooler than you think.
That dude from CT Yankee in King Arthur's court was so freaking lucky lol
I saw the 2017 eclipse in my front yard in Oregon. It was one of the neatest things ive ever seen.
The world went quiet. All birds, all insects all silenced. Then it got dark. And everything got cooler.
It was terrific.
Same here in Nashville! That was my senior year of high school and they let us have that day off. We went to the Football field and it was perfect. Not a cloud in the sky. One of the most incredible experiences I've ever had. So sad I have to work on the day of the eclipse this year :((((( I'll be 44 years old when the next one comes around
I had seen partial eclipses before, so I figured it was all hype or "cool but not THAT cool". After seeing totality in 2017 I now understand why old stories of predicting eclipses were viewed as religious events. It was amazing.
I traveled from Seattle to Oregon just to see it, and it was awesome! I'll be visiting family in Cleveland this year.😊
All of this, exact same exp, exact same state
I so wish i cud see totality this yr, but i cant afford to travel rn even tho ive got the time and its actually gonna pass thru the state i now live in; just the other end of this less than an oregon sized state
Its an unimaginably cool experience if youve not seen it; and indescribably cool if youve seen jt
Same. I didn't even have to travel to see it, but I went a little further south to be in it for a few minutes longer. Wound up in a random field on the side of the road with 3 other cars. Absolutely awe-inspiring. What I found coolest, besides the eclipse itself, was that we were in the middle of what I can only describe as an all-encompassing sunset. You could see the hills around us tinted pink in all directions with us dark in the middle. I'll never forget it.
You can't make homemade glasses, but you can make a homemade pinhole camera to project the eclipse on a surface of your choosing, assuming you can make it sufficiently dark around the projection area
I remember doing this at school in the 90's for a total eclipse, it was so cool!
a surface of your choosing... except anyone's retina!
During a partial eclipse I just used my hands to make a pinhole, shadow puppet style. It is actually pretty cool to see the projection change into a crescent shape as you make the hole small enough.
I did this with the last eclipse (that I was in a place that I could observe it) with two paper plates! They were the sturdy white fibrous kind and they worked great! :)
If you are under a tree with dappled shade from the leaves, it's cool to see a the shadows all get a little bite out of them during a partial eclipse.
The reason it still hurts your eyes as much as it would if there wasn't a partial eclipse is because your eyes are adjusting to the visible light and not to the UV light. So your eyes end up bringing in a ton more UV light by comparison. Also, don't go buying up all of the welding glass, it's cheaper to get the disposable solar eclipse glasses and you can reuse them if you just fold them up and put them in a safe place
Is the whole of the eclipse dangerous in that regard or is it just the transition between partial and total eclipse? I think I've heard that you can actually look at a solar eclipse without glasses if all you can see is the sun's corona, i.e. you're in the path of totally and the sun is fully covered up by the moon
@@rfldss89The only time it’s not dangerous is for the few minutes of totality when you have to take off your eclipse glasses or you won’t see anything.
I put my 2017 eclipse glasses in a very safe place. So safe that I can't find them now 😎
Ah the old "put them in a safe place" trick.......they'll never be seen again
@@kilhapuritybold ok, yes, but still, unless you're gonna be using it on the regular, needlessly driving up prices for welding PPE is not healthy for the working class budget.
The 400x bigger and 400x further thing to make the moon the same size as the sun is wild. I love the moon 🌝
Fun fact: Hank first taught me this fact... In a song where he also sung about how to load a dishwasher xD

I did learn the answer to the danger question several years ago, but totally agreed on how poorly it's always explained because it always drove me nuts when I was younger. The sun is *clearly*, *demonstrably* less bright during a solar eclipse, why is everyone acting like it's suddenly so much more dangerous?! And when someone *finally* put it to me like "No, it's exactly as dangerous as looking at hte sun always is, it's just physically EASIER to do during the eclipse." And, that made perfect sense, and I then I was mad that no one said it like that before, lol.
I also enjoyed that description of lagrange points.
Meanwhile Aztec sun gazers: 🗿
But mostly because we all really want to look at the sun.
It is not actually easier to look at it, even at 1% it is still too strong to look directly at it. So it is more likely that the damage is due to using fake eclipse glasses or sunglasses.
I got one…
How do you organize a solar eclipse party?
You planet.
I experienced the 2008 total eclipse in China. It was a normal school day... until it pretty suddenly wasn't. We ran outside into the weird day-night, eerily absent the sound of birds. It was smoggy, so our viewing glasses were useless, but the experience of just being there, surrounded by classmates, teachers, and darkness, was more than remarkable.
Edit: corrected year
I never considered that smog would be worse than clouds. I'm lucky there's no smog here.
that's funny considering there wasn't a total solar eclipse in China in 2016
@@mapledoctor3915 oops! You're right. It was 2008. I was 16, hence my mistake. :)
I was also there teaching for that one. Even with the smog it was such a cool experience.
I think this is the first time within 4 years that the word, corona, is being used with excitedly positive sentiment.
The Matt Mercer fit. Powerful.
Thanks, can’t unsee it
I'm glad I'm not the only one to think that!
I think the thing that surprised me most in the 2017 eclipse (I camped out in Southern Idaho for it), was how cold it got so suddenly. Like it sounds so obvious that it gets colder without the sun, but what I didn't realize was how much of that heat is actively falling on you, not just sitting in the atmosphere around you. Less than a minute after totality, the temperature drops *precipitously*, like probably multiples of 10s of degrees (it felt like it dropped 15-25 F for us), and it's the thing that sits with me most to this day.
I saw the eclipse in (Edit) Georgia and had the exact same experience. The temperature drop was really unnerving.
Summer, a warm bright morning, and my hands felt frozen in 3 minutes of totality
That was weird, but cool. The way the shadows on leaves look when almost at totality was also weird.
I'd forgotten that! It was in August in 1999 and I was wearing August clothes! Just as well it lasted less than 5minutes
I also experienced it in southern Idaho and I just wrote a comment almost exactly like this lol The temp drop was incredible!
I love that this is earth's fascinating quirk. If we were from any other planet, discovering earth, it would be on the list of obscure science facts about earth.
_"Jupiter's day is only 10 hours long, which is the shortest in that system. Pretty neat"_
_"Earth's distance from the sun and its moon align just right for a thing called »total lunar eclipses« to happen"_
So much so, that if we ever found ourselves in a galactic community and needed a flag or logo for planet Earth, a diagram of a total eclipse would be unique enough for us to use without ambiguity.
@@jamesrockybullin5250Is that true though? Couldn’t a smaller sun or larger moon also have a similar effect?
Total Solar Eclipses are the hard one. Lunar isn't that hard cuz the moon is tiny lol - Lunar means the earth is casting a shadow on the moon.
God-designed for His purposes.
@@lindawalkup6084 Wonder what purpose He made eclipses for.
I work at a utility in Arizona and we absolutely saw a major decline in solar production during the October 2023 eclipse
I mean, fewer photons means fewer photoelectrons...
More than an overcast winter day?
I love that each person sees the corona differently because of their eyes being slightly different. It's like the sun is saying something to you specifically. It's so cool!
Heraclitus…
If you do drive to the path, take spare fuel, food and water.
Between 30 and 50 million people are going!
Please make sure you're on a hill/mountain so you can actually see the moon's shadow race across the land. That's the best part!
Unfortunately I think large hills are hard to come by for most of the path of totality. I'll be on a small hill surrounded by woods, hopefully I'll still be able to catch that!
@@IndyJay53 as long as your view isn't blocked by the woods, I think you should be OK. I've only experienced this once by accident (in 1999) but I recommend just looking down at the view towards the west (by southwest) in the last few seconds leading up to totality. The shadow will going 720 mph across the ground. Let me know how it goes! For comparison, if I remember correctly, I think this was my view at the time so not much of a hill either: www.google.com/maps/@49.4734016,5.2214433,3a,75y,226.88h,89.41t/data=!3m7!1e1!3m5!1s3oT92gAf6cThE58gwG7jDg!2e0!6shttps:%2F%2Fstreetviewpixels-pa.googleapis.com%2Fv1%2Fthumbnail%3Fpanoid%3D3oT92gAf6cThE58gwG7jDg%26cb_client%3Dmaps_sv.tactile.gps%26w%3D203%26h%3D100%26yaw%3D282.07462%26pitch%3D0%26thumbfov%3D100!7i16384!8i8192?entry=ttu
Am from Ohio, can confirm is very flat. You’d probably have to go over to Maine in order to get that effect, or maybe somewhere between Buffalo, NY and Erie, PA where you can overlook Lake Erie
I personally think the coolest part of an eclipse is how the outside shadows get otherworldly sharp. Really cool, so cool I wish I lived closer to where the eclips is happening.
Plus, you can see the eclipse happening under trees. The leaves make great pinhole projectors.
HANK. I witnessed the 2017 eclipse in totality very much on a whim thanks to my science obsessed brother. It was miraculous. There are no words to properly explain the experience.
These past few months I've been SOOOOO tempted to make the drive to the zone of totality, but everyone around me talked me out of making the trip because A) I'm about 6 hours away and B) I teach high school and it's testing season, so absences are highly discouraged.
Your enthusiasm is giving me the most intense FOMO. I'm tempted to channel my rebellious teenaged self and just friggin do it. Screw logic and responsibility! I want to witness magic again!!
Do it.
This opportunity comes just once.
Well, this is my third.
I can't really remember the first, making pinhole veiwers in grade school, no glasses.
2017 was amazing when the light shining down through the trees cast little dancing crescents all over the ground.
Don't miss the magic.
Wish you could take your students.
❤
Dude! Go! 6 hours is nothing.
I’m in Europe... that’s far away.
My teacher mom and I are driving 8 1/2 hours to see it. Really a can’t miss experience if you like science and it won’t happen again for a while!!
it’s looking to me like the next decent total solar eclipse coming to north america is in *2044.*
do it. you won’t regret it.
Do it!! I'm a teacher, too! Your students won't remember those terrible tests, and in a couple of years, neither will your school district. If you play hookie and then come back with your stories about the experience, your students will absolutely remember your joy. DO IT.
I experienced just over 2 minutes of totality in the Great American Eclipse.
I understood the science of what was happening. I'd seen pictures, read articles, watched videos.... None of that prepared me for the absolute MAGIC! No one can really describe it... it's very moving.... one must experience for oneself. It's entirely understandable why people in olden times were shocked and scared!
OF course, you see the difference, but it doesn't just get darker... all the reds and yellows fade, and the world turns a bit blue, and it gets cooler. The sounds change, too.... birds go quiet... insects start up... Yes... in just those few minutes of totality or near totality...
Stay safe, don't look without the CORRECT glasses (We got some you can comfortably watch TV through.... YIKES!!!!! We replaced those!)
I think it was the most magical moment of my life! (other than the birth of my daughter) ... It's worth taking the day off... pulling the kids from school.... driving a good distance!
I REALLY HOPE it's not cloudy in Cleveland!
As someone from Ohio, it’s Cleveland, so it probably will be 😂
I am extremely sad right now. So my dad lived in Tennessee and was right in the path of totality in 2017. He's never been somebody to gush over anything but he made it a point to tell me that it was the most magical and life-changing experience of his life. After that phone call, I googled when the next one was going to be, and I saw that my house is going to have three to four minutes of totality for this eclipse. I couldn't believe it, I was so excited! But... I'll never get the chance to tell him that he was right because he passed away last year. So I feel insanely connected to him by what's about to happen on Monday. I just looked it up... Local weather people are predicting zero visibility. Like no shot of actually seeing the eclipse. I'm standing outside right now in the most beautiful day imaginable and I have to continue into the weekend knowing that I'm not going to get to see it.
As you watch it, you’ll cry at how your jaw drops with awe, so glad he told you to do it…
please try to drive out for a better chance at visibility, it may be really inconvenient but i promise it’s worth it
Come to Illinois.
Accuweather says it's the best day of the weekend. Mostly sunny in Wayne County.
It will still be amazing because it will go black unlike it does in clear places. If you can get to a hill, do that so you can watch it go black in a line over the earth.
The weather reports could absolutely change between now and then. Be on the lookout anyway on Monday, just in case.
01:34 - I think Hank got this backwards. When the Earth/Moon system is further away from the Sun the apparent size of the Sun is *smaller*, and thus the Moon is more likely (it has an elliptical orbit around the Earth as well, so its apparent size as seen from the Earth also varies) to be able to fully cover the Sun.
The Earth(/Moon) is closest to the Sun in December, furthest away in July. So Total Solar Eclipses will happen in Northern Hemisphere Summer more than in NH Winter. To have an eclipse you need the Sun to be visible, i.e. it to be daytime, and there's more of that in local Summer.
To be fair, he later states this around the correct way, so just a brainfart in the moment I think.
As for the perma-eclipse, it'd be a LOT more than just being mean to one guy. It'd really do a number on life on Earth in the shadowed region.
you're right. there's a minute earth video ua-cam.com/video/1GrOLainIiA/v-deo.html
@@AthAthanasius It really depends on whether we want the perma eclipse to be static relative to the planets surface - if we did, it'd have to be tidally locked and that has a whole lot more effects than a permanent eclipse would. If the planet was still rotating, we'd just have a big shadow sweeping across part of the planet and not really doing much harm
@@AthAthanasius He got it backward the second time around, too, saying that the Earth is closest to the sun during the Northern Hemisphere summer, which isn't the case, and if it were it would cause fewer eclipses in the Northern Hemisphere.
Came here to say this
I love how Humankind went from being abjectly terrified of a solar eclipse, to exhibiting unbridled joy. I always love it when people clap and cheer for Nature!
So you're a total solar eclipse virgin! I can't wait to hear your thoughts and impressions of it and, of course, if you clapped and cheered!
From my understanding it varied a bit from culture to culture. Plenty of ancient civilizations had a good enough understanding of the movement of the moon through the sky that they understood that an eclipse was just the moon passing in front of the sun. In a world with no light pollution and few accurate maps, the sky was the often the best way to navigate.
SOLAF ECLIPSE VIRGIN. i love this term
Don’t overestimate humanity. Some of them are still religiously freaked out by eclipses :/
My family and I live in Ellettsville Indiana so we’re prepped to just stay in over the weekend see the eclipse from our home, while we let all the travelers go through town. It’s exciting for me to experience
we’re in cleveland doing that with some close friends! so exciting indeed
I’m to be in Bloomington, anticipating traffic blockade! My son says get there Sunday night to avoid it…
Yeah, my area is expecting 1.5x as many visitors as people who live here. It's gonna be PACKED!! Still wondering where an extra million people are gonna fit.
Concerning the constant eclipse and the stability of the Lagrange points: some of the points are just like Hank said - unstable. But there are stable Lagrange points, namely the L4 and L5 which lead or trail the body by 60deg in orbit. They are called Trojans and they can get pretty big. The largest one being 624 Hektor which is an approximately 250km diameter Trojan around Jupiter's L4 point. The Earth has Trojans too, albeit much smaller. However as far as an eclipse is concerned the 60deg offset would mean they never come into the line of sight between the sun and the orbiting body (like Earth), and thus they would never produce an eclipse.
As for the permanent eclipse, it would be possible. If the planet was tidally locked to its parent star (not the case for any planet in our solar system, but is possible) and had a moon on a distant orbit, orbiting with the same speed as the planet rotates, it would cast a permanent eclipse over some part of the planet. If it could be total however, idk. Would need to do some math. Maybe Scott Manley would know.
Edit:
Scott Manley: "I have not been able to come up with a stable system where a spot on a planet is always eclipsed."
I guess that a tidally locked moon/planet system that was on a perfect flat plane with their sun would have a eclipse every rotation.
Maybe it would me more likely for double planets?
9:22 - I like to imagine alien tourists flocking to Earth to watch our eclipses, because they can't see a star's corona anywhere else in the galaxy.
Near Akron....didn't realize it was gonna be like 2.5 hours of action. Even more excited now.
most of the "action" is hardly noticeable, and NOT noticeable without eclipse glasses. And then repeats after the 3-4 minutes of totality
4:44 A quick addition that I don't think gets talked about enough: the reason you get told this during an eclipse even though it's just as dangerous to stare at the sun any other time is that the dangerous thing is to *stare* at the sun. If you glance past the sun, if you just have the sun in your field of view for a second, that's not a problem, your eyes can deal with that.
I feel like people often don't wanna talk about this because it feels like endorsing staring at the sun, but not saying that it's specifically staring that's the problem confuses people like the question asker who do see the sun briefly every day and don't perceive any sense of danger from that. The reason it's not dangerous on a typical day is that if you're not really motivated to stare directly at the sun, your "ow my eyes hurt" instincts will tell you to stop staring way before you get eye damage from staring at the sun. But when there's an eclipse, people *are* really motivated to stare directly at the sun.
I saw the 2017 eclipse. Everyone who can, please, please do yourself the favor and go see this one! It is such an amazing experience, I promise.
if you don't have glasses you can use a colander (or anything else with small holes) to see the eclipse in the shadows!
The circular shadows will become mini eclipses. It's very cool looking and I recommend looking at the cool shadows even if you do have solar glasses
I was trying to figure out why this particular eclipse was so special. Thank you for this video!!
Curly hair and now vests with tees?? Truly a new Hank
This will be my third total solar eclipse. First in my back yard when I was 7-8. Dad made us glass viewers by smoking the glass with a candle. Second on in Toronto in the ?early 90’s using a pinhole device. On the 8th I’ll be in a field with my daughter and grandkids, special eclipse viewing glasses, in my southeastern Ontario town. Since I’m 70, it’s likely my last, but I’ll be happy I shared the wonder of the solar system with another generation! 🇨🇦🖖🏻🇨🇦
Great video, Hank! I've been basically watching only eclipse-related videos for the last few days and I still learned a few things! This will be my first total eclipse as well (hopefully not my last) and I'll only have to drive an hour south to be in the path of totality.
I've been waiting for this for nearly thirty years. On may 10th 1994, I was 8 years old, and my entire school was taken outside to view an eclipse. I thought it was total at the time but later learned it was only about 85% (and was in fact not total anywhere). They mentioned to us the next one in our area would be in 30 years, which of course is an insane amount of time when you are 8, but I've been looking forward to April 8, 2024 ever since.
I also look forward to your post-eclipse video!
Beginning my drive from Washington State to Indianapolis tomorrow. I know flying would be cheaper, but road trips are fun! Very excited. Maybe see you there Hank!
Have fun! We are doing the same with my nephew.
I did a road trip for the 2017 eclipse. I get to see it from my back yard this year!
Any time excited Hank shows up to talk passionately and explain thoroughly, I enjoy it.
Hank
Hank what would an eclipse look like from the moon
Hank I gotta know
I would guess that watching the earth, you could see a little shadow travel across it, over the course of several hours.
relative to the size of the earth, the shadow would be very small, but otherwise it would be similar to a lunar eclipse as viewed from earth, nothing will really change on the moon since it's not a significant amount of light that's prevented from being bounced back.
I guess on the other hand, a LUNAR eclipse would be pretty intense from the moon. The earth is bigger than the moon (citation needed) so it'd block out the sun even more completely than our solar eclipses here on earth
A solar eclipse seen from the far side of the Moon would look like a lunar eclipse seen from the day side of Earth.
@@aaaaaa-ts3rwyeah exactly! the entire moon would be eclipsed too, there wouldn't be a specific area you would have to be in to get a total eclipse.
also would last quite a bit longer
There are pictures of eclipses seen from the International Space Station, and there's just this big round shadow on Earth. Should be something like that.
Hank you look great! I'm glad you're still here. Thank you for everything you do. You make the world a better place.
I went to the one in 2017 with my now husband. And we’re going again as a full circle kind of deal.
Full circle. Ahah.
Not quite the same... Esp bcuz the two of us cant see it this yr despite bein so close to it; just lack of funds to travel despite the time
But me and my soon to be husband (he/they) actually kinda watched the last eclipse in 2017 together
We didnt know each other then, but the eclipse went over both the cities we live in, despite bein halfway across the continent from each other; so we both were able to watch it together
He watched it with their late husband (he); who was an awesome man and i loved havin him as my metamour for the short time i did before cancer unfairly took him four yrs ago
I had watched the eclipse with a roommate (he) and his family who had taken me in, a complete stranger, less than a yr before; and who also introduced me to an awesome little community called nerdfighters. A community that has made me grow to love this sorta stuff even moreso; and to enthusiastically and unabashedly experience such things without worry about if it makes me weird or nerdy or any other thing deemed wrong by so many
Great explanations! Quick correction on one point: the northern hemisphere's summer currently aligns with the part of the Earth's orbit when it's further from the Sun. That makes the Sun appear smaller from our viewpoint and therefore easier to block.
The thing you want closer to the Earth is the Moon. Its orbit is also elliptical, and when it's closer, it appears bigger, meaning it's better able to block the Sun.
Thanks for the vid Hank! Happy Eclipse!
Only 4 more years until the 22 July Solar Eclipse! The path of totality goes right through Sydney Australia and Dunedin NZ.
All I know about Dunedin is the murders on Every Street.
pro tip if u don't have glasses you can see the shape of the sun by poking a small circular hole in a paper plate or something. It will cast a shadow in the shape of the partial eclipse.
Or just use our hands, shadow puppet style, and see the crescent shape appear as you make hole between them smaller.
13:30 I attended the total eclipse crossing Cornwall in 1999. Totally cloudy. The weirdest thing. You can see the horizon fully lit up and watch the shadow of the moon on the clouds above. Utterly surreal experience. Very different from the 2017 eclipse in Tennessee which was clear. Looking forward to this one, the weather is looking very promising for us here in Eastern Canada.
I saw the one in 2017
Same in school
Same! My school got us all glasses and took us out to the field to watch
Me too, but I think I did it wrong. It was and humid and I kept having to go back inside the house for I don’t remember what reason.
@@Anna-Bin my area most schools cancel classes because they don’t want to be responsible for keeping kids from damaging their eyes. (Average class size of 32 students is way too many kids for a single teacher to supervise when some of them certainly are prone to self-destruction)
Europe 1999 checking in. It was cloudy so we chased the bastard trying to find a gap in the clouds. Found a chink in the armour and pulled over, shit got real, animals all went quiet then started acting bizarre, making weird calls. Super dark and spooky, turns out we'd driven accidentally into Germany where we saw it, from France. I'm not sure how much of the weird phenomena can be attributed to that fact.
My girlfriend and I experienced the last total eclipse, but we broke up because we saw each other in a totally different light.
I work at a major international airport near the path of totality
In the last 4 days, I have seen customers from every state except weirdly Hawaii; every European country in the European Union,Schengen, or NATO; every Canadian province save PEI- well long story short people aren’t just driving to the strip of totality they are coming in from around the world.
I have a likely untrue and hard to prove theory that this is most widely observed anything (Coronation, football game, tv show, fireworks show, rodeo, parade whatever) in all human history.
It's crazy to me that I'm 26 and I saw a Total Solar Eclipse before Hank Green. What stopped you in 2017? It was cloudy where I was for much of the eclipse, but it was still an exceptional experience. The mere fact that it goes from being like midday (depending on time obviously) to being like midnight is incredible. Being able to experience that shift in minutes is a profound experience. Everyone should experience a Total Solar Eclipse at least once in their lives, and it depresses me to see people who have the ability to go to one and choose not to. Even if you'll see like 98% where you are, that is ridiculously different from totality. Totality was the closest I've had to a truly spiritual experience. We happen to live on a planet where our star is almost exactly 400 times larger and almost exactly 400 times farther away from our moon and it crosses behind it sometimes. That is truly exceptional. Please seek out any eclipse you have the opportunity to go to. Even Annular Eclipses are very cool (my first one was in October).
I saw totality in 2017. Seeing totality is one of the very few things that not only lives up to the hype but far exceeds. It really is life changing. The most unbelievable, awe-inspiring, beautiful, spectacular thing you will ever witness. Once you see it you “get it” and realize why people will do ANYTHING to view it again.
Additional reason looking at an eclipse is MORE dangerous: being darker out, your pupils are more likely to be dilated and letting in more light, exposing your eyes to more photons in that small portion of your retina. It's like increasing the size of the magnifying glass you're using to burn something.
The main thing that ive learned from this video is that eclipses are hella complicated and the fact that they happen at all is insane!
Several years back we were in the path of totality. 15 people came to stay at our small house for it. It was amaizing the hype is real. Heads up, the wave of darkness happens fast.
I'm luckily living on the path of totality and I can't tell you how excited I am to see it.
I'm so glad you exist at the same time I do. Your videos are the best
I'm reading Circe right now, and its awesome to see helium was named after Helios that way.
Hank, I'm genuinely SHOCKED that you didn't travel to see the 2017 eclipse. I expect it to be in my top ten experiences until the day I die. I hope you get great weather tomorrow!
Dating my self here, but I was in the 8th grade when I saw the total eclipse in 1979. It is absolutely one of the coolest, but also an eerie phenomenon. I remember asking my mom if I could stay home from school for 2 reasons. One was that I wanted to experience the eclipse without all the other kids in my class around. The other was I didn't trust my 8th grade science teacher. He had told us we were going to go outside and look at it as a class. He had done other questionable experiments,, where we had minor accidents/injuries so it worried me. (I became a teacher BTW) It went dark, like a really bright moonlit night. All the animals went silent, no chirping birds, barking dogs, etc, extremely cool, but eerie. I've also seen several partial eclipses. If you do not have eclipse glasses, you can still watch the movement of the moon over the sun with 2 index cards. It's not as amazing as looking directly at it. To use the index cards: poke a small hole in one index card with a pin or toothpick. Stand with your back to the sun. Hold the card with hole so the sun is shiny through the hole. Put the other card behind it so sunlight goes through the hole and onto the second card. Adjust the space between them so the bright sun spot is visible. You can watch as the moon slowly obscures the sun. Like I said, it's not as magnificent, but if you don't have eclipse glasses it's possible to watch the event. It works for partial eclipse as well.
wow how did i not connect Helium with _Helios_ before??? thanks for teaching me something new today, Hank!!! (hope your recovery from the you-know-what is going well)
I agree, how did I never figure that out?
I love those little "aha" moments.
8:53 This is the most crazy part. I don't believe in god or the simulation but like what the actual frack. The odds must be so small.
There's a recent MinuteEarth that goes over this pretty well, and I recommend checking it out.
There's just a huge number of planetary systems. What's really crazy is that an eclipse planet also has sentient life.
@@jajssblueOur moon is unusually large relative to the size of the Earth which might have even contributed to the evolution of life in various ways, such as protecting us from asteroid impacts.
Thanks hank! This was great and I learned a lot. Always so impressive how you can explain this big concepts in accessibly simple ways
In the 2006 TV show "Heroes", it is implied that a total eclipse was a catalyst for people getting super powers. What the heck was that all about?
Edit: The L1 (and L2) point, which is the Lagrange point you’re talking about, is actually passively stable on two axes, but not the third. It is not a maximum, but a saddle point. There is a sort of plane that is described by a normal vector pointing from L1 to Earth. You are stable on this plane, but if you move towards or away from Earth, you are no longer getting pushed back onto the point. This is how JWST orbits the L2 point: it is not centered on the point, but lies offset in the plane such that it orbits around L2 on this plane, getting pushed back towards the center as if there is a gravitational body there. It only has to forcefully keep itself located there by thrusting towards or away from Earth (assuming two-body physics).
/Edit
A more plausible solution (assuming the Earth wouldn’t burn up in the sun or the moon wouldn’t be so large the Earth/moon system became a binary planet system) could be if the moon’s orbital period was the same as Earth’s, it could perpetually cast its shadow. A lot would be very different if that were the case. We would probably need the sun to be a lot cooler so that Earth could be a bit closer, then have the moon be larger so it could be farther away but maintain the size ratio. These two changes would speed up the Earth snd slow down the moon.
Anyway, the path is a very boring one where everything is nearly identical except the altitudes such that the periods of the moon and Earth are equal…
Hey Hank, I think you had it the wrong way round when you said that the Earth-Moon system being further away means fewer eclipses. Surely the sun would then appear relatively smaller, so it would be easier for the moon to fully obscure it?
PS love your content and infectious enthusiasm!
If you're at 90+% occlusion, then it won't get that dark, but the color of the world definitely changes noticeably. Calling it dusk doesn't do it justice. It's more like being in an old movie. Also, shadows get super weird. If you look at the shadow of a tree, it'll look like a bunch of circles piled in each other. It isn't as weird as the eclipse proper, but it's still an experience worth checking out.
Thank you for this!!! It answered so many questions. I am so very excited to see it!!
I live in the DFW area and i'm going with some friends to a spot that will be in the center of the path. looking at over 4 minutes of time. Super stoked. Until i've been watching the weather forecasts that are all saying almost all of texas will have cloud cover on Monday 😭 hoping for some breaks in the cloud around the time. also, we have a plan to drive this north south highway looking for a break. fingers crossed.
Same 😢
I just looked it up and the weather channel is showing everything from Texas to Southern Indiana being under heavy cloud cover, there are going to be a lot of disappointed people I think.

to answer the flat earth thing, my friends dad simply doesn’t believe in space
Very cool! Thank you for the detailed answers to my questions Hank :D

Hope you get good conditions with your solar eclipse dude, they are nuts. I recommend it near somewhere with a lot of wildlife, like a wood or park, somewhere with a lot of trees and birds.
Eclipse shadows from the leaves are so beautiful and interesting
@@sanachantoIt's true, like shadows at twilight or when there's a full moon. I was more thinking about the animals' sounds, they go quiet but then get confused and start making weird noises. Maybe it's the nocturnal ones waking up haha idk
As of right now the weather channel is predicting extremely cloudy over most of the path of totality with clear bits over western Indiana and north west Ohio.
Also pretty good perdition for western and north eastern New York.
Unfortunately everything from Texas to southern Indiana is supposed to be heavy clouds, as is central New York and Most of Maine. Things can change but right now its not looking great for most of the US.
My wife and I were going to go to Dallas to see it but given the forecast we decided to go to my Aunt and uncle's house in rural Illinois, which is directly in the path of totality and is supposed to be much more clear
I'm going to be heading south to central IL around Effingham and it's supposed to only be about 25% cloudy. Hopefully I-57 isn't totally jammed all day by Chicagoans doing the same.
Where do you see this on the Weather Channel? Planning on going upstate New York but weather is still a concern, need to figure out where will be the best to watch it.
I do wanna pt out; even if things are cloudy, there is still a huge exp to seein the eclipse. Someone in the comments even mentioned seein the 2016 eclipse in China and it bein still amazin even tho the smog and clouds made it impossible to see the sun eclipsed
Its still amazin to experience how much colder and more quiet the world becomes when night dawns in the afternoon
@@Pikachu0071000CS wunderground has detailed cloud cover predictions.
The last total solar eclipse we saw in southern Ontario was when I was in grade 3 almost 30 years ago. My son is almost the same age I was when I saw it. Just so cool.
I saw the total eclipse yesterday parked on the side of a tiny road next to a cemetery along with my family and four other cars of people. There was patchy cloud, but enough that we could watch the sun get smaller and smaller; it was covered at the moment when totality began, but the clouds got just thin enough to see the corona _just_ before totality finished. It was freezing. It was amazing. The solar lights in the cemetery decorations came on, and the streetlights, and we could see high clouds still lit up like day even though it was dark for us.
"i think that you can visualize what i'm talking about" - i don't have a mind's eye hank, i certainly cannot visualize what you're talking about. but i appreciate you trying!
I am severely disappointed in the amount of answers on my honda eclipse questions.
I tried to see the 2017 eclipse in St Joseph, Missouri, but got blocked by clouds. Managed to drive around for a while and find a thin spot in the clouds, as totality hit, getting just a brief glimpse of the corona through the haze - a blurry ring with a couple distinctive spikes I later recognized in other people's photos. Unfortunate, but it was still an impressive experience - the 360 degree sunset, the pale eerie light and distorted colors, temperature drop and breeze, and animal behaviors were still very evident, and surreal. I'm doing my damnedest not to miss this one.
Traffic was also very impressive... Especially in an RV. Be careful out there.
I am overwhelmingly excited about this being a possibly huge moment in the history of solar physics!
Were the solar probes purposefully sent there to be in the right place at the right time specifically with this eclipse in mind?
how did i get here 55 seconds
edit: i apologise for not using this rare opportunity to say something more original
edit2: last time i was this early the fuckin uhhh moon blocked ou the sun over the us. thats topical
I’m so disappointed in you
Did the sun gods specifically target Johns house for this eclipse? because it looks like it tracks directly onto John's house just so you can go visit it and do cool science.
I found a good analogy to why looking at the sun during an eclipse is more dangerous. It's like not wearing sunscreen when it's either cold or slightly overcast. We associate sunburn with hot summer and bright sun so if the air is keeping your skin relatively cold or if you don't have that sensation of the sun beating down on you you're not going to think to slather yourself in sun block. A lot of people get sunburned if go skiing and don't know you need to put sunscreen on
I'm so excited!!! The partial in 2017 was cool, but totality is SO close we're traveling this time.
Hank i love your channel but ,your description of how the eclipse happens using your hands was like watching an Italian mom yelling at her kids.
An orange and a marble might have worked better....lol
Thanks Hank. Very informative, interesting and entertaining, as per usual.😊💚
You were correct, it was really cloudy in Texas then suddenly in the last minute the clouds went away and we saw the totality of the eclipse.
I'm so hyped to see the eclipse! A total solar eclipse was one of those things I thought I'd never experience because they're so rare in any given spot, but it turned out that both the one in 2017 and this coming eclipse pass pretty dang close to where I live. So now in a few days I'm going to be seeing my second solar eclipse!
Hey thanks for the warning. Coworkers are watching the eclipse today, but today I wasn't scheduled to work, so I didn't go in. I didn't plan on getting my own eclipse glasses. I thought about using sunglasses, but as you stated, I do not want to burn my retinas for the entirety of my natural life. Guess I'm gonna miss out, oh well. Enjoy safely everyone else!
Great info, well delivered, and with infectious enthusiasm! ☮
I've always wondered if staring at the eclipse was worse than staring at the regular sun, but I've never been able to find any answer's so thank you for that.
Some animals do act fairly weird during an eclipse, there is a actually a study of it happening during this one for the first time in a few decades. Anton Petrov has a great video about it!
I saw a tweet replying to someone asking what the hype for the solar eclipse was, they said if interstellar tourism were a thing we'd have aliens coming to earth by the shipload because of how unique eclipses are. It's such a crazy coincidence that the distances and sizes are so perfect that this can happen.
Thanks Hank! Brilliant and helpful and wonderful as always!
I watched the Aug 2017 eclipse from the beach at Road End in Lincoln City, Oregon. The eclipse was fantastic, plus if you looked the other direction over the ocean there was a "Fog Bow"
Thank you for answering for someone from AZ because we were much closer to the last one and I was nervous this one would be uneventful!
Finally. The answers we needed and wanted. 💕 Thanks Hank 💕
Looking forward to this one! My husband and I traveled to western Missouri for the 2017 eclipse, and it was such an amazing experience! This time we're gathering with family and friends at an AirBnB that I booked last year in south/central Indiana. Hoping for relatively clear skies. When my father was alive, astronomy was a huge passion/hobby of his, and in his retirement he had a relatively fancy telescope (for an amateur) that he had a sun filter for. My sister now has it. We borrowed it for the 2017 eclipse, and she's bringing it to our gathering for this one, too. Yes, we have our eclipse glasses, too.
Thank you Hank! When all my family lost faith from all the clouds I held out hope and it was RIGHT IN THE POCKET!! Beautiful experience!
Back in 2017 we drove to a country road going through a corn field in rural Missouri. We got a total eclipse and it was a totally awesome experience. It was eerie the birds started singing, the cicada got loud it felt like the evening and the quality of light was totally odd. i'd recommend it.
You hit the nail on the head about how cool it is, you dont understand unless youve seen it
From my experience, cows lay down and try to go to sleep during a solar eclipse. Afterwarda they just get up and continue eating grass like nothing happened
I love your enthusiasm, Hank!!
I’m still bummed I didn’t see the 2017 one, so I’m flying out for this one. I’ve been obsessively checking the weather all week.
