I don't know if you are going to read this Phil, but anyways I would like to thank you very much for this series. You managed to make astronomy more interesting to the masses, and you did it by not making it too hard to understand. I am a civil engineer and I love astronomy,physics and math. So I felt very happy to see this, and I hope we have more episodes of Crash Course Astronomy. (also recomended to some friends interested in astronomy to watch this ASAP!) A big fan of yours, André Gomes
i found a small iron meteorite last summer.....about the size of a prescription bottle's lid....and when i found it, i was like a little kid on Christmas!! it looks very different to the hematite we have locally. i sat here with it in my hand watching this vid, like a child. the thought of holding something so amazing is near spiritual for me.
TheMrMeff No scientist is considering *crashing* a space probe as a possibility. Instead, the space probe would attach itself to the meteor and alter its trajectory.
I've been rewatching the MST3K catalog this week since I'm between jobs for the first time in over a decade. That line before the opening hit me right in the feels. Thanks, Phil.
Thanks so much for making these! My astronomy professor at college has us watch these along with his lectures and I understand everything so much better after watching them
Very nice video! Me and my brother actually had a discussion about a year ago, while stargazing during a meteor shower. We both saw a ghostly streak after one of the bigger meteors, and wondered if it was either debris/dust or if it was just an afterglow in our eyes. Glad to get some of that clarified! :)
You *HAVE* to do videos about the history and future of spaceflight please! (And also a possible video about possible past missions that could've happened, like NASA's 1980s Mars missions.)
Back in AZ, I have a 9-pound meteorite. It is about the size of a softball. Its mostly made of iron. I'm bummed out I forgot it there. Some day I hope to go back and get it.
***** Oh, puh-lease! The relation between birds & bird-hipped dinosaurs is much closer than that between primitive bacteria & humans - well, in most cases...
***** the thing is that ***** is actually right. Birds are technically dinosaurs so they technically did not evolve from them (I'm not saying birds didn't evolve from some of the species we normally call dinosaurs). They are dinosaurs by definition, or taxonomy :P
+ㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤdinosaurs were not a species. They were part of the clade dinosauria, making them dinosaurs. A clade is just a common ancestor an all of its descendants. This makes birds dinosaurs since they descend from some of the species of dinosaurs that lived millions of years ago. www.pnas.org/content/109/7/2428/F4.expansion.html
Phil was in Sydney last year and I remember going to his talk at the Observatory here, and he actually bought along a piece of Asteroid/Meteor (can't remember which one, it was so long ago) for us to hold!
We need to go into space and mine those asteroids. Here in the US, we can pay off our debt if we just mine two one mile long asteroids. This has a great economic impact but also one of security, we would have to worry about one becoming a meteor and smacking the planet if we just mine it into none-existence up in space.
That would make the economy worse. Flood the market with RARE materials. That's the only reason they are expensive is because they are RARE. Gold would be the same price as tin. lol
Josh Hooper they would still be useful. Gold and other rare earth metals are used for all kinds of technologies. If we could get them from space instead of destroying our planet then I'd be all for it
kingofprussia17 bigger problem is the outer space treaty meaning nobody can actually OWN anything in space and that " the exploration of outer space shall be done to benefit all countries" which this doesnt do. The treaty explicitly forbids any government from claiming a celestial resource such as the Moon or a planet, claiming that they are the common heritage of mankind.
I know someone who is into fossils and she's friends with a meteorite collector (he jokingly called her and said he was flying to Chelyabinsk right after it happened). She's really lucky because he lets her have some of the dust he collects whenever he cuts into one. She's made some beautiful pottery that's been finely sprayed with meteorite dust. She's also generous, so I have a couple pieces with meteorite dust them as well. :)
I came upon Crash Course by way of SciShow. I have an unending curiosity to the extent I’m pretty sure my first word was “why”! (Granted that got me into more trouble as a kid but thankfully that trouble couldn’t kill the curiosity!) Speaking for myself, I must say there’s something addicting about learning when the person teaching truly loves their topic! Most people find it strange that I prefer videos like these but have little to no interest in watching tv. My thought... why watch fiction when reality is so much more interesting, fascinating and even frightening!? The only thing I can think of as a “tweak” to this series... I’d love for there to be ‘add ons’ as new things are discovered. Other than that, I love the series and appreciate everyone who works to make these available! Thank you!!!
I rather like the idea of attaching probes onto them to push them into new orbits so you don't end up with lot's of hard to account for and harder to control pieces of exploded space rock potentially hurtling your way. Plus if they contain any useable minerals they can always be pushed into a stable orbit and exploited.
Thank you very much for making this video, Phil Plait and the others at _CrashCourse_ Astronomy! I really love this series and I really love astronomy! Meteors are also fascinating, very fascinating. I have a hard time remembering the difference between meteoroids, astroids and comets but I think it will eventually come to me. Did you say that a meteor catastrophe, when a meteor larger than 100 m in diametre hits Earth, happened every two or three CENTURIES? Oh, we better get busy finding a solution and selecting a course of action, otherwise we will be in a real mess...

There's a Magic the Gathering card named Meteorite. The art shows it already on the ground. Sooo, it's accurate! I'm happily surprised.
I saw Lyrids and Eta aquarids meteor shower this year and for that I came across this video to understand what's happening! Now I am watching the entire Crash Course series and it's fun during this lockdown! Thank you very much Sir! 🙃
Any tips/thoughts on meteorite hunting? I'm talking about when you hike through the desert and find a verrry unique rock that turns out to be not of this world, not the flying to and mining gold/iron/water from them in space.
Mandlize I guess that comes down to luck. But everytime there is a farely bright meteor spotted, there is a search for a possible meteorite. Just about 2 months ago, there was a very bright bolite going (visible in daylight) and there was a huge search for it. After few days they found this tiny (about 1 cm in size) rock.
But don't worry! They'll be stopped by a young adult who suffered extreme trauma and for awhile thought he was a completely different young adult. When they call forth Holy, summoned by a cute girl who is now all kinds of dead. Also along for the ride we have Mr T, Ninja Girl, Evil Robot Cat(tm), Mr Tea (shut up and drink it, damn it), Morgan Freebobcat, Emo Git, and Tits McGee ...it's a long story
But then the hot boy turned out to be the host of another stronger, hotter boy who swing around his very long sword against the young adult with his big sword as they talk about their past. Then the young adult get fed up with the hot boy and be like "disappear to where you belong, in my memory" while dumping him after a flashy break up.
At my local(ish) planetarium, they have this shiny chunk of rock about two/three adult fists big or so, with a sign saying "This is a metallic meteorite that fell in (place) in (year). See how heavy it is!" and it's attached to this sliding rod thing so you can lift it a bit. Probably lots of planetariums/science museums have something like that, but I still think it's cool that ordinary people can just walk up and touch a chunk of outer space. :)
Here's an emergency plan if such meteor comes and we are still unprepared: Step 1: Open the door Step 2: Get on the floor Step 3: Everybody goes the way of dinosaur
yes the air in front of it will be compressed at incredible speed rate and generating a lot of heat, but I think the friction of the air with the meteor itself also generating heat. You know every friction generate heat, even the compressed air get the heat from their own atoms friction.
Interesting watching this and hearing that we are helpless to the universe. Now in 2022 we successfully changed the period of an asteroid orbiting another asteroid with the DART program. We can fight back!
I saw a bolide meteor during the day time, I was at a campsite somewhere in South Africa and it passed over the horizon, I remember the front part being bright white with an orange tail (which I thought was fire) streaking out behind it. It left after images in my eye once it was gone. I'd love to see one again some time...
I really wonder who would downvote a video like this. It's so weird. Almost anything else I can understand, but educational, non-annoying videos like these?
Meteors are nature's way of saying "How's that space program coming along?"

Underated comment
There's an even better way to piss off astronomers:
"hey, can you do a horoscope for me?"
Love how Phil teaches you how to piss off astronomers XD
"What's your sign?"
Genius! XD
Haha! I love that part!
I don't understand that! Can someone explain me how that can piss an astronomer!
@@arnavjain7566 By sign they mean horoscope sign, which is an attribute to astrology, not astronomy. People sometimes confuse this.
With the DART mission, we have now tested our ability to redirect meteors and asteroids
This is gonna get lost here but i love how this channel is dedicated to education and sharing information. Really awesome
JaeDogg 🙄🙄🙄
Indeed!!
I wish Crash Course would release an illustrated book for each completed course.
Oh, my god, I would buy the hell out of that. It would be so adorable, as well as educational!

Ok, so now whenever I'm going on a car trip, I'm gonna say, "let's haul mass!"
i found a small iron meteorite last summer.....about the size of a prescription bottle's lid....and when i found it, i was like a little kid on Christmas!! it looks very different to the hematite we have locally. i sat here with it in my hand watching this vid, like a child. the thought of holding something so amazing is near spiritual for me.
Every meteor website looks like it was designed in the 90's
Looked up into the sky and got blinded by street lamp, instructions not clear enough.
Both funny and extremely depressing.
Looked up into the sky and saw: Streetlights and clouds.
Instructions clear but not followable right now. :\
More tinfoil!
- So, you collect rocks?
- Jesus Marie, they are meteorites!
minerals
Whoever is responsible for the mst3k reference deserves 3000 high fives. Nicely done, whoever you are, nicely done.
This is silly but I didn’t realize shooting stars were actually particles entering our atmosphere...😱 so cool 👍💫
Scientist -
"let's crash a space probe into it"
American -
"Nuke it"
TheMrMeff and american scientists want a nuclear space probe?
TheMrMeff Well, America does have a lot of nukes lying around in Europe. Might as well free up that space for new models.
ㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤ Why not? It worked for Voyager, Galileo, Cassini....
TheMrMeff No scientist is considering *crashing* a space probe as a possibility. Instead, the space probe would attach itself to the meteor and alter its trajectory.
Monochromicornicopia Deep Impact? On the very 4th of July, 2005? Not to alter its trajectory, but still.
The dinosaurs went extinct because they didn't have Bruce Willis in their space program.
A tragic oversight.
Probably due to budget cuts
A few non-astronomy reasons I love Phil: 1) he references MST3K. 2) He calls it the doobly-doo. 3) He quotes Larry Niven. :D
I've been rewatching the MST3K catalog this week since I'm between jobs for the first time in over a decade. That line before the opening hit me right in the feels. Thanks, Phil.
Thanks so much for making these! My astronomy professor at college has us watch these along with his lectures and I understand everything so much better after watching them
If one's headed towards us, won't a team of oil riggers led by Bruce Willis blow it up in impractically stylistic fashion?
No, Chuck Norris will tell it to go back to the asteroid belt and be a good meteoroid.
Aconserva jones damn right.
Quixotic1018 Only if NASA can afford to license Aerosmith songs.
Quixotic1018 Yeah, but we would loose Bruce Willis in the process. That's just too high a cost.
I wish you talked about the Tunguska event. No, not the one resulting in the spread of an alien black oil.
Not as ticked off as when i shout "pluto is a planet!" while running through the room.
I'm totally geeking out over your use of an MST3K reference.
"Can we get this on Still Store, Cambot?"
MST3K reference at the beginning.
Phil Plait is my hero.
haha "hauling mass"
As an Engineer Student this joke makes me happy. :)
Love the MST3K shout out. Now we just need to check Rocket number 9.
AH! love the mst3k reference!
"Cambot, can we get this up on still store?"
My heart grew three sizes today.
0:29 I never thought I'd see a MST3K reference on this channel. Well done. I officially love it even more now.
Very nice video! Me and my brother actually had a discussion about a year ago, while stargazing during a meteor shower. We both saw a ghostly streak after one of the bigger meteors, and wondered if it was either debris/dust or if it was just an afterglow in our eyes. Glad to get some of that clarified! :)
I love how I’m learning more about astronomy from this guy in 11 minutes than my college professor in 50 minutes
YAAAAS!!!!
MST3K REFERENCE!!
YOU ARE NOW OFFICIALLY MY FAVORITE PERSON!!
If KSP tells us anything, it's that all you have to do stop the meteor from crashing on earth is to put a giant rocket on the meteor to shove it away.
Michael Hughes if ksp taught me anything its drag astroids toward your planet

While I very much like the quote, it's not technically true, since we still have dinosaurs today in the form of birds.
***** They must have a space program
***** Oh, puh-lease! The relation between birds & bird-hipped dinosaurs is much closer than that between primitive bacteria & humans - well, in most cases...
***** the thing is that ***** is actually right. Birds are technically dinosaurs so they technically did not evolve from them (I'm not saying birds didn't evolve from some of the species we normally call dinosaurs). They are dinosaurs by definition, or taxonomy :P
***** they are descendants of dinosaurs, but are only classed as a subgroup of dinosaurs, not the 'real thing'.
+ㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤdinosaurs were not a species. They were part of the clade dinosauria, making them dinosaurs. A clade is just a common ancestor an all of its descendants. This makes birds dinosaurs since they descend from some of the species of dinosaurs that lived millions of years ago.

Hey Phil what's your sign?
Νίκος Μοαβίνης ... he said tick off an ASTRONOMER! (Idiot...)
He is an ASTRONOMER(Idiot...)
yup mr scorpion fan, he is an astronomer. bet some smartass's feeling dumb now hm?
DjMoelder please shut up or I will report you and every UA-camr you love, unless I like them too.
Mileena and Scorpion Fan he is obviously joking.What your problem with a joke?
"Cambot, can we get that one still store?"
love the subtle MST3K reference.
0:26 Cambot? Who do you think you are, Joel?
I was sure Phil was going to say the easiest way to tick off an astronomer is to ask him about Pluto's planetary status.
lol, I love how things are named in astronomy "oh it's a meteorite that's comprised of stone, lets call them Stoney meteorites!"
Woo! Larry Niven mentioned in this! Excitement and fangirling :D
Very nicely done! Thanks Phil!
I watch the eclipse last night,it was awesome.really cool :)
Phil was in Sydney last year and I remember going to his talk at the Observatory here, and he actually bought along a piece of Asteroid/Meteor (can't remember which one, it was so long ago) for us to hold!
we have links to some in the doudly doo lol, love this series
"up to 70km/sec or more"
Darn it CrashCourse! That's literally every velocity : p
Oh lordy... now they've got Phil saying "doobly-doo."
I recently saw a shooting star in Spain. It was very bright, and so impressive.
New favorite phrase: "Hauling Mass"
We need to go into space and mine those asteroids. Here in the US, we can pay off our debt if we just mine two one mile long asteroids. This has a great economic impact but also one of security, we would have to worry about one becoming a meteor and smacking the planet if we just mine it into none-existence up in space.

Josh Hooper they would still be useful. Gold and other rare earth metals are used for all kinds of technologies. If we could get them from space instead of destroying our planet then I'd be all for it
Josh Hooper However, if we had a steady supply of these materials, we'd simply redefine the economy. There's still S&D.
kingofprussia17 bigger problem is the outer space treaty meaning nobody can actually OWN anything in space and that " the exploration of outer space shall be done to benefit all countries" which this doesnt do. The treaty explicitly forbids any government from claiming a celestial resource such as the Moon or a planet, claiming that they are the common heritage of mankind.
USA DE-RATIFY THE D**N TREATY
thank you Phil, i learn something new with every show
Anyone else see the Persiads this year? Best meteor shower I have ever seen in my life.
John Deads yes, on a really dark island!!
Anybody agree with me that this is CrashCourse's best series?
Cambot, Gypsy, Crooooooooooow
"Best way to tick off an astronomer, as them hey what's your sign?" --- OMG this is both hilarious AND true!
I know someone who is into fossils and she's friends with a meteorite collector (he jokingly called her and said he was flying to Chelyabinsk right after it happened). She's really lucky because he lets her have some of the dust he collects whenever he cuts into one. She's made some beautiful pottery that's been finely sprayed with meteorite dust. She's also generous, so I have a couple pieces with meteorite dust them as well. :)
See, I thought I knew everything worthwhile about comets and asteroids, but I never thought to look up what caused meteor showers. Cool.
Yes! MST3K reference bomb!
Mst3k reference and Kerbals, cool
I came upon Crash Course by way of SciShow. I have an unending curiosity to the extent I’m pretty sure my first word was “why”! (Granted that got me into more trouble as a kid but thankfully that trouble couldn’t kill the curiosity!)

Ha-ha when he said meteors travel in packs, I'll I could think was tunnel snakes rule!!
I rather like the idea of attaching probes onto them to push them into new orbits so you don't end up with lot's of hard to account for and harder to control pieces of exploded space rock potentially hurtling your way. Plus if they contain any useable minerals they can always be pushed into a stable orbit and exploited.
You get a like just for the MST3K reference alone ;-)
I CANNOT wait until New Horizon passes Pluto & its moons in a couple more days so you guys can make their very own video about it! ♥ Super excited!
i think phil might have been the best guy to do this.
thought i couldn't love crash course any more
and then: mst3k reference
I reckon I saw a bolide above Melbourne some time around 2000, but never knew it had a special name until now.
really helpful, thank you!
Up to 70 km/sec or more? That's every speed imaginable!

CC Astronomy is quickly becoming my favorite Crash Course program. Keep up the amazing work.
07:04, what about the Tunguska event?
I really love your work. Thanks a lot !
These are great micro lessons. For people that like to learn about science in general.
I saw Lyrids and Eta aquarids meteor shower this year and for that I came across this video to understand what's happening! Now I am watching the entire Crash Course series and it's fun during this lockdown!

This video brightened my day. Get it? brighten. .... I find my own way out. :c

What happens when a meteor hits Earth and drains the lifestream?
We'll get psychotic emo hot boys that run around killing people looking for their Mother.
But don't worry! They'll be stopped by a young adult who suffered extreme trauma and for awhile thought he was a completely different young adult. When they call forth Holy, summoned by a cute girl who is now all kinds of dead.

"I LOVE ASTRONOMY "
-PHIL PHLAIT
WHO LOVE😍😍ASTRONOMY LIKE ME AND HIM????
👍
👇AND I REALLY LOVE THE INTRO BGM I WANT THAT
Here's an emergency plan if such meteor comes and we are still unprepared:
Step 1: Open the door
Step 2: Get on the floor
Step 3: Everybody goes the way of dinosaur
I saw a 'shooting star' years ago while I stood outside my house. It was awesome.
Mentioned Larry Niven; automatic thumbs up for referencing the co-author of Lucifer's Hammer.
i love watching meteor showers they are beautiful to watch
"It's because they're hauling mass....you heard me!" 2:00
Hauling mass.... Took me a second to realise you didn't say "ass" XD
Thank you so much for the knowledge i will use this for my science project
Shoutout to the DART mission!!!
yes the air in front of it will be compressed at incredible speed rate and generating a lot of heat, but I think the friction of the air with the meteor itself also generating heat. You know every friction generate heat, even the compressed air get the heat from their own atoms friction.
At 3:33, that is the coolest thing I have ever seen!!!!! Thanks for great content!
I watch these in school it's awesome
Interesting watching this and hearing that we are helpless to the universe. Now in 2022 we successfully changed the period of an asteroid orbiting another asteroid with the DART program. We can fight back!
Cambot, haha, nice reference
"Hey, what's your sign?" LOL so true
+CrashCourse I love your videos , they're awesome !
If you manage to get your hands on a meteorite ,know that you have the ultimate pet rock
I saw a bolide meteor during the day time, I was at a campsite somewhere in South Africa and it passed over the horizon, I remember the front part being bright white with an orange tail (which I thought was fire) streaking out behind it. It left after images in my eye once it was gone. I'd love to see one again some time...
2:00 wow I should check out meteors more often
I really wonder who would downvote a video like this. It's so weird. Almost anything else I can understand, but educational, non-annoying videos like these?
