- Опубліковано 30 тра 2024
- The Sun... both the giver of life, and destroyer of worlds. Host of the eight planets, and incubator of Earth with its light and heat. Yet in spite of its brilliance, the true nature of the sun's power remains shrouded in mystery, with scientists unable to explain many of the processes playing out in its atmosphere. But in 2024, NASA will attain their closest glimpse of the sun so far, as they come just five million miles from its surface, diving into the stellar Nether Zone, to "touch" the sun itself.

It's wild to think that a single light photon, from the sun, takes nearly a 100,000 year journey from its core, to it's surface , but then only 8 minutes to reach Earth. I love physics.
Lots of matter to bounce again and again, then its free willy.
That doesn't even make sense.
When a photon is absorbed and then later another photon is emitted again, it's not the same photon emitted that was absorbed.
Photons don't travel from the core at all. There is no way, even in principle or theory, that we could track a photon making this journey. It's an entirely conceptual model, not empircal, certainly not a fact. A model, and...
That model isn't accurate at all.
It makes even less sense when you realize a photon is just a potential probability in a wavefunction until we observe it...
@@Xirrious a paradox!
Yeah and relative to the photo no time has passed from it’s emission to its impact of our eyes or sensors
@@Xirrious illuminating
Praise the sun! 🌞

I love the way the earth rotates on its axis, it really makes my day.
🙏
😅
i like that
It makes my year.
You're right, I messed it up. It's fixed now lol@@thanatos8618
i've already liked this despite not watching a second. this is my bedtime story. SEA does the best bedtime stories.
I m a bit into the video already, but the like is a given.
So glad one day I stumbled over this channel
Night night pals!
Lying down to fall asleep to this ❤
SEA uploads, I click like. It's simple.
Except when you're into it, you fall asleep and your phone lands on your face.
I hate how SEA seems to be shafted by the algorithm. Never gets recommended to me, always have to find them myself, always great videos
I watched 1 video last week and now all I get are SEA videos. No complaints though.
ahhh i’m back to my comfort channel
“NASA is going to go back and touch the sun when it’s nighttime” 🤣🤣🤣
Well yeah its not as hot at night *obviously*
Better visibility due to less shimmering from heat haze. Really all of this is common sense. I really am at a loss to fathom how it consistently seems to be right here within the comment section that the greatest insights are to be found.
Cheeky monkey 😂
@@SofaKingShit…what? if you’re APPROACHING the sun to touch it, there is no night time because the sun is always in view. Unless you mean something else?
@@echowhosthis really? 🤦♂️
Thank You SEA so much for making the best space documentaries on YTube.
"It's 93m miles to the Sun, we got a full tank of propellant, half a pack of heat shield tiles, it's dark... and we're wearing sunglasses."😎
Fantastic video, great work and a joy to watch.
Is that a blues brothers reference?
The Sun’s outer shell will impact our Earth at appx 1550 miles per second (+/- 5 1/2 million miles per hour. 17-18 hours to travel 92,800,000 miles.
Don't forget to pack 4 whole fried chickens and a Coke 😎
@@user-jn3sz8zo8goh blues brothers, you just took me far back to very found and cherished memories

"Hydrostatic Equilibrium"
Why do I love this word so much
I can't stop saying it
Ya, I gotta say that more often.
That's two words.
@@deusexaetherawell look at Mr 'i can count to two' ova here.
...show off.
Give this man at least at least 5 million subs. Great work, thanks man.
studing the sun at night.... ah ah ah good one!
I've used this twice as sleep aid now, 10/10
SEA I am surprised you didn't talk about the granules. The popcorn looking things riding on the convection currents. Never the less another.....stellar video.
He did talk about photosphere convection cells, same thing, although only in passing to explain why switchback mass emissions are helium enriched.
29:40
Close-up photos of the granules are absolutely stunning. It's amazing how something that appears so static and constant here on earth visually is really more like a rolling boil that spits water all over the stove, rather than a simple glass of water.
Also the water is intensely magnetic and will someday grow to engulf your entire home, burning you alive. Fun!
I'm a simple man. I see a new video from SEA and I watch and like it.
Ugh, you're simple alright
So the sophisticated men have no monopoly 🤓
Quite illuminating
I see the Sun...my eyes get absolutely annihilated 😢
But SEA gives me an awesome video about the Sun so I don't have to stare right at it to appreciate it's beauty! 😍
I don’t think there’s a UA-camr I get more excited to watch these days!! I always watch around bed time bc it locks me in and relaxes me at the same time. Keep up the great work SEA 🌊
when i first found your channel i realy thought this was just gonna be some random ass space asmr shit or something
but i was pleasantly surprised to find that you are a phenomenal science communicator, keep it up man
One of my favourite lunch break things to do, if I don't have a documentary or something to watch, is to pull up one of NASA's Sun timelapses. Such a mesmerizing thing to watch.
Oh my god YES Finally! Ive never been able to find a good in depth video on UA-cam about the sun (if anyone does know of any others I'd appreciate it.) My son (ha) has been more interested in space lately and I told him I would keep an eye out 😭 Hes gonna love this thank you.
Loving the plural aurorae. Thank you for that vernacular
HelioPhysics!!! First time I hear the term... I like it!
Praise the sun and the SEA ❤
The sun is so fascinating. There is a movie called Sunshine that's pretty good. It's like The Core mixed with an Event Horizon vibe but the sun version.
That actually sounds pretty good 😁 I believe I shall watch that 👍
Sublime from start to finish. Thank you!
We love your videos man. thanks for all your content. I am a single parent and me and my daughter have watched almost every one of your videos LOL She loves em.
Me and my kids also watch Sea together at bedtime ❤️ they are huge fans too ☺️
The excitement i feel when the notification beeps and it's SEA!
You're honestly the best there is..Riveting stuff. Thank you so much.
I am not a smart man, but I do love this channel and everything THIS man creates. Just jibberish to me, but also, amazing. No matter how hard I try to listen and understand, the more I DON'T. But would like to.
Is that you Forrest?
Nobody understands everything about the Sun, smart or not. I share your sense of wonder.
With open arms, with cheers and song, with joy in my heart and tears in my eyes! Praise be to Helios, this is a glorious day for Whiterun and for all Skyrim!
Thank you so much SEA
Thank you for the engaging and incredibly informative video.
I wish we could witness in real time, and from distance not too far, the explosive birth of a star.
As always awesome and I wish it was a longer production.
Thank you for another awesome Vidya.
Just want to say that as a long time fan, im really happy to see you doing well with your switch from gd content after all these years.
Much love❤
Outstanding work yet again by the people at sea, such in depth discovery should be shared to a wider audience,extremely entertaining and the underlying science is bang on point. I can't understand why no broadcaster has put you on TV but there loss is our gain. Thank you for being a leading light in times where we seem to celebrate mediocrity, keep up the inspiring videos 👍🏻👍🏻
I’ve been hyped for this one all week! Thanks for the top tier videos!!
This might be your best video yet
Nothing makes me feel my ADHD like these videos. I'm rewinding every 2 minutes
Hahaha that's so stupidly true, I'm trying to sleep but my mind hears one word or sentence and either races away or end up getting stuck on that thing, I have only manage to get to about 6 minutes even to I have been laying here nearly 40 mins cuz I keep on needing to rewind every minute 😂😂😂
Sweet! Yet another space video to watch. Thank you for this. Can you do a video dedicated to pulsars and magnetars if you haven't yet?
Love that Sun
So complex, so lovely
I’m a simple man. I see a new SEA, I click.
It's like it's not even a thought. SEA puts out a new video and I'm watching it already.
As usuall. Excellent and exquisite. You Sir are by far the best Channel out there! :)
Probably my favorite topic. You presented it masterfully. I've watched it at least five times so far.
Great job on this one (and all of them).
Fantastic video as always SEA. Thanks for the content.
Pretty remarkable how important our sun is to this planet.
important? if the sun dies we follow suit in 8 minutes and that cold-400C blackness dark interspace that follows for a lifeless earth for eternity probably.. DEATH IS SWEET COMPARED TO THAT consider that at night, there;s a lot of light coming only from him, all around the Earth, is just that at night light doesn't come at us
Great video as always. I absolutely cannot wait to see what the Parker Probe finds during its closest approach. Maybe in a couple of years, you'll be able to make another video featuring a lot of new and spectacular scientific findings and images.
The Sun is a wondrous body, like a magnificent Father!
If only i could be so grossly incandescent...
another banger from sea. thanks once again. learned a lot from this one. a lot of effort - it is appreciated. top shelf research
Here we go! Been waiting a week for this. Light her up Sam 😘🔥☀️
From Geometry Dash UA-camr to this masterpiece, you've truly come far!
From SEA to shining SEA video, this was AWESOME.
The BEST videos on all of youtube!
I hope we’ll see the first man walking on the sun within the next 10-15 years 🙏 Humanity is ready for it. ☀️
lol
Just land at night lmao
The*
Don't let your sun go down on me
@@jaffaxlthanks
This was awesome. Don't piss off the sun!
The legend of underrated channels is back!!!
I love this channel and space stuff. I also remember laughing uncontrollably as a teen when i first heard the phrase "coronal mass ejection"
Great content my friend, very educational and interesting 👍 👌
Excellent, as always. I learned stuff.
"Kaneda! What do you see??"
Goodnight 💤
Brilliant video I'll be looking out for the pictures. I love the humour at the very end
Definitely a hot topic.
of all the natural things i have seen, the Northern lights in Iceland are top of the list for being utterly amazing. there’s no photo of video footage that captures it particularly well either. i imagine the event that created these across the world was mind blowing
…and the knock on affects would be really, really bad, at least we would get the light show end all light shows along with it
Good one, love to dream away at these videos
Great video, interesting how you give the medieval measurements(miles) involving the world countries, good for you.
stay awesome!
Hi, just wanted to comment before I start watching this video. Of my 100+ channels I sub to, this is one of two or three that I stop what I am doing when I see a new video posted, grab my headphones, and listen. I love this channel, I love these videos and I am so grateful for you making them. Thanks!
Here is some more info to go with this excellent video:
Sun - a solo, oddly calm, G2V Type yellow dwarf Star here
Power sources
-loss - Photo-disintegration of deuterium (also called photo-transmutation) causes power loss as atoms break up to a simpler state. This process keeps on going through all the stages of the Sun, but speeds up as more energy is produced, then when it shines dimmer as a White Dwarf the reaction happens less.
-loss -The slow neutron-capture process, or s-process creates new elements/isotopes at a cost of energy like in Red Dwarf Stars, but over thousands of years for each atom. This keeps on going through all the stages of the Sun, but faster as heat increases.
-loss - as the Sun heats, it sends out the Solar Wind/exosphere which takes energy/loses mass. This happens more as the Sun gets brighter.
+ gain has initial temporary power from gravitational compression at the start of its life.
+gain -Radioactive Decay like what happens in planets also give a teeny amount of energy. Yes, the Sun has heavy radioactive elements inside it, like Earth.
+gain -Free Deuterium(Hydrogen with a neutron) & free Lithium fusion burning, like Brown failed Stars, have finished very quickly as our Star starts.
+gain -After that the proton-proton chain/PP fusion is the main source of power, making more new deuterium,. which is then fused into helium-4 per the Deuterium Reaction; but it happens more quickly than in Red Dwarf Stars. The PP chain initiates at about 15 million K in the core.
+gain -the CNO reaction (CarbonNitrogenOxygen) catalyst makes Helium-4 is also present, but scientists argue about how much (0.4% to 10% right now). The CNO catalyst reaction becomes dominant at about 17 million K or in stars 1.3 times more massive than the Sun.
future Sub giant stage - the core gets clogged by helium “ash” elements in electron degeneracy, so Fusion reactions start moving outward, with makes our yellow-white sun bigger and hotter giving off more Solar Winds mass..
future Red Giant stage
Helium Fusion is next after Hydrogen is gone, causing the outer shell of the Sun to expand.
+ gain -After Helium-4 is made the core & sun shrinks and then carbon forms via the Helium Fusion Triple Alpha process. This reaction is simple. Two Helium-4 nuclei (aka alphas) Fuse together and form Beryllium-8. This Beryllium-8 nuclei is further Fused to a Helium-4 and forms a stable Carbon-12 - this reaction requires a temperature of 100 million K.
-loss -As the Carbon “ash” builds up, the electron degeneracy causes a second red giant stage. During the last stage of this reaction the Sun has thrown off it outer shell into a planetary nebula.
Future White Dwarf
After our sun finished creating Carbon and it has thrown off it outer shell into a planetary nebula, it’s left over core is too small to go any further. It collapses into a white Dwarf, all the Carbon possibly ends a huge hot carbon electron degenerate (diamond like, but much, much heavier) core.
+ gain -possibly a thin layer of Hydrogen or Helium remain, with a little Fusion going for a while.
+ gain -It cools and begins to release heat of crystallization as main source of energy. Unless it gains more material to burn on the surface from a nebula.
Example Sirus B
Future Black Dwarf
After it cools too much, no reaction occurs, no left over heat is left to glow, the Sun would be come a cinder.
----------------------------
The Sun, a spectral class G2V main-sequence star
99+% mass of solar system; Helioseismology (echos of vibration of sun-quakes seen in light) shows the layers:
a. 20-25% Core {CNO 1-10% of energy & the rest mostly pp fusion followed by deuterium fusion ending with fusing 2He3 to stable He4 - about 2/3 of the Sun’s Hydrogen has been used up in the core, 2/3 is already Helium; also >0.1% is radioactive decay/Lithium burning/fission},
b. ~50% semisolid Radiative zone {also has some reactions which produces >1% of fusion energy}, thin Tachocline border below which the Core & Radiative zone plasma rotates as solid and above which the plasma layers act as fluids, and in Tachocline some scientists think is the source of the Sun's Magnetic Field.
c. ~25% fluid Convective zone still 2/3 hydrogen and 1/3 helium, other scientists think the Convective zone is where the Sun's Magnetic Field originates.
d. observed Photosphere/(surface) sometimes with 11 yr sunspots [And Sun’s surface does not act as a solid, different latitudes rotate differently, 25 days at equator, 31-35 days at poles - also the plasma flows to poles at surface and below the Photosphere the plasma flows deeper but slower back to equator.],
e. Chromosphere the reddish ”lower atmosphere” where temp rises,
f. Corona [where magnetic field rules the plasma finally, below this the plasma pushes around the magnetic field, and here temp shoots way up.], and
g. Heliosphere/Solar Wind/plasma/ interplanetary medium (which goes out past the planets to Heliopause); The Sun’s magnetic field squeezes in on the side so that more high speed jets of matter and energy from deeper in the Photosphere exit out of the Sun’s poles, this is the cause of the Heliosphere croissant like shape; also the Sun’s magnetic field flips every 11 years - cause unknown. The Sun's Magnetic field goes out to the edge of the Heliosphere along with the Solar Wind. The Magnetic Field interacts with the Solar Wind to slow the Sun's rotation over time, but soon it should stop, given what we have seen in other stars as they age.
h. Sun's interplanetary (HMF) where the Sun's gravity still rules, but the local nebula's [yeah, we are inside one] plasma and magnetic field rule out to the theoretical Oort cloud; The dwarf planet Sedna orbits way out here along with the Voyager probes leaving.
[Note: stars 30% of the Sun mass are thought to have no radiative zone, only the core and convection - and stars 1.2+ more massive than the Sun it flips with no outer convection zone, only radiative, but the core itself becomes convective.]
Extinct Comets and asteroids impact sun, or close in orbit perigee 100+ per year, most unseen except for IRIS & IRAS solar satellites.
We'll you make an interesting point......😁 and succinct too.
Im a simple man.... I see new SEA video, I get serotonin flood
Awesome video thanks for that keep it up mate love your content educational and enjoyable been waiting for the update on the Parker probe I'm extatic to find this out
I look forward to being part of the sun one day. Here is to being a future sun fart! 🥂🍻
Goodnight
I really enjoy your videos. I look forward to your next.
What a AWESOME AWESOME video.THANK YOU so much.
YAY! Hello again!
The Sun is the seed of life for us 💥👀
finally a new video to fall asleep too! lol ur vids are my sleep aid
NEW SEA VIDEO DROPPED
As always great work SEA.
I wonder what is the noise of a star. Thx SEA for another brilliant video
Incredible work, great video, thank you.
I’ve watched this 5 times and plan to watch it again in a few days :) you are gifted. We don’t need the Emmy’s or Golden Globes to tell us what to watch.
This video was really informative. Looking forward to your next videos.
Most Underated channel
As always a Brilliant video!
Great video
Truly great quality.
SEA - SUN
👏🏾👏🏾👏🏾
Had never heard of that solar flare event in Canada. The game "the long dark" makes much more sense now
I was not prepared for that ending lmao
Awesome. Ty SEA
Love your channel.
That was brilliant thank you ❤
Makes me proud to be a human being.
Thank you for another fascinating most informative video.
i love all your videos thank you!

Yaya! Best creator on the Tubes! Thanks Mate!
The metaphor with enstrument string was really good.👍
Stunning production and delivery on the story of our sun, which is estimated to be one of 10😊0 billion in our galaxy alone
Thank you!! 🤸🏻♂️
