Please don't ever change the general idea of your intro tune. As soon as I hear it my mind goes into learning mode like I'm pavlov's dog. Keep up the great work!
I'd just like to thank you, and say that my daughter took an astronomy class in college, and she's learning much more from this series than she ever did in class. I can attest to this, since I audited several lessons. They were using a textbook from 2004 (and this was two years ago), and the teacher had absolutely no idea what she was doing. I felt kind of bad for her. I would have felt worse if I hadn't been paying so much money for it. I'm learning a great deal as well. I've always been interested in astronomy, astrophysics, and cosmology. I was too sick to attend college long enough to get to any of what I actually wanted to learn. It's always been a huge regret. So thanks for giving me the chance to learn more now. It means a lot to me.
Darkrai Titanollante Technically there's nothing physically impossible in living to, say, 5'000, it's just rather unlikely. I am simply going to be that infinitesimally rare occurrence. Sure it kinda assumes the laws of probability will bend themselves around me, but that's the outlook of most humans anyway.
Phil, that was my favourite so far. I'm writing sci fi (with real science) and your sessions are super helpful and reliable. I've always felt that stars were underrated. The planets, being about 0.14% the solar system's mass, are just the largest chunks of the Sun's debris field, lying well within its extended atmosphere.
Besides well written content, Phil is really a great host, who speaks at optimum pace and tone for comfortable listening. He also makes appropriate jokes once in a while which is unlike other hosts of crash course who just happened to let jokes overrun their show and confuse the audience. Great job, Phil, keep it up!
I absolutely love crash course astronomy. I love all crash course episodes, but astronomy is my favorite. Phil, you do an amazing job and you make the astronomy lessons very interesting, though it helps that astronomy is like the most interesting subject in the universe already!
This episode was fantastic. I've watched a thousand 1hr long TV documentaries that just show lots of pretty CG graphics and dont really explain the lifecycle of a star all too well. But this episode was perfect and i actually learned ALOT that i hope will stick =D
Thank you for this series. Because of it, I checked out a book from the library on astronomy, went to an observatory, and saw Saturn and two of its moons. Never too old to learn.
thank you. yet another very informative and highly entertaining video. Narrative is superb (Super or even Stellar) as is the soundtrack !! well done. More please.
So there was this new guy I never heard of coming over to do crash course about one of my favorite subjects. I was prepared to be disappointed. I love being proven wrong. This is by far my favorite crash course series and I desperately hope there is much much more coming.
I really love that phil has kerbals figurines on his desk. This game is amazing to understand how space travel works, and if an expert in astronomy backs it, it show how accurate it can be. ^^
Hello Phil Plait of Bad Astronomy! Love the chapter in your book where you are deflating the thing about average stars. Without a doubt our somewhat modest star is about a B+!
Thank you so much for this video! I have never heard such a detailed lesson on what happens to star! I would LOVE to see something like a time lapsed video of an artist's impression of all the different phases the sun will go through, like slow motion videos of flowers unfolding. Even if the video had to be rather long, I would be rapt at see how a star grows and shrinks and gets hotter and cools and how it's gravity changes. How 'bout it?
Every episode my mind is blown. Please make episode on 1. Pluto and dwarf planets 2. Faux moons of earth 3. Ring system around planets/asteroids 5. Black holes 6. Proxima and alpha centauries and planets around them
I have to say love what you do here I have both adhd and dyslexia so school was a bit of a bummer for me and even though I’ve always found science and history extremely fascinating I stilI had problems learning and getting into them because of the way they were taught but these videos are great educational tools that help so much keep up the great work guys
Another valuable learning vid... Thanks for the word definition for paroxysms in video, I would have had to stop the vid to Google it :). Keep up the good work!
MAN I would be 100% OK with this being twice per week! Don't get me wrong, I love every episode every week as is, I'm just being greedy for more. Ya'll convinced me to take an Astronomy class at Uni recently and I love that too! Thanks CC Astronomy team!
Wow Phil, thanks for that ive never seen anyone else go into so much detail, congrats to yr educating skills cos even i stuck with ya all the way thru.
It's absolutely incredible! I have never used this channel before. I am Physics student and this is sooo useful to understand the concepts of my Stellar Structure and Evolution course, so I can get the "intuition" and big picture, that is the most important thing in Physics! Thank you SOOO much =)
Welp, if you have a telescope, just point out to the Scorpio constellation. The brightest star, Antares is a red supergiant. Or point it to the Orion constellation, as Betelgeuse is also another Red Supergiant (Which may have aready blown into a supernova )
You know it's because of this video that I finally started to understand how Stars fuse stuff together LOL. And how and why the star models were like convective Zone conductive Zone and all of that stuff. I understand now, this is awesome... it makes sense for a red dwarf to flare out more than our sun. When you think about it... if they are completely convective, then the stuff happening in the core will always make it to the surface
So basically the sun will turn into a huge diamond? I mean except it will probably be plasma towards the center.. Sounds really cool. I'd like to watch stuff drop onto its surface once it has cooled down. Should be fun :)
basically yes! There is a white dwarf somewhere which has been named "Lucy" by astronomers. it is a reference to the song by the Beatles "Lucy in the sky with diamonds"
***** Oh goodie! Not to forget that all our heavier elements came out of a supernova anyway :) ***** Thanks for the refresher. I wasn't sure the term _degenerate matter_ applied here
Life cycle of the low mass star: Protostar > K or M type main sequence star > dimmer and darker star > White dwarf star > black dwarf. Protostar > F or G type main sequence star > Red Giant > Helium Burning giant > Double she'll red giant > Planetary Nebula > white dwarf > black dwarf.
The name of the episode is a bit misleading. When it says "Low Mass Stars", I expected to learn more about Red Dwarfs in general and how they're different from other stars like the Sun but instead, this episode mainly goes over the Red Giant phase of Sun-like stars. This episode should've been named "Red Giants" instead.
Sebastian Gauthier Technicallg speaking, a Red Giant Can be less massive than the sun, Give or take how much mass it has for either a super nova or a stellar remnant, of which the sun will expel the latter and become a white dwarf
So I have a question, in episode #22 it seemed that you alluded to a possible future episode about Pluto. Since that episode was posted only a few weeks before New Horizons was to make its historic flyby. Now that the probe has made that flyby do you plan on producing an episode covering some of the stuff we learned from that probe? I know it will take years to fully analyze all the data gathered, but maybe an episode about the preliminary stuff including the up close pictures of the planet and moon?
"will fluctuate wildly over very short time frames" -- Often, when astronomers talk about short time frames it's millions of years. So it would have been good to say what was meant by this phrase in the video.
SuperSaiyanMaze A high-mass star is generally one that is roughly twice the mass of the sun and above. They live out their main sequence as stars normally do, but as the hydrogen gets depleted, they start fusing helium into carbon into neon into oxygen into calcium into iron. After that, one of three things can happen. The star can implode in on itself rapidly, but not fast enough that it's so sudden, and it forms a pulsar. Or the star can rapidly implode itself and form a black hole. OR, if the star is massive enough (Say, Betelguise massive...), it's known as a Type II Supernova, destroying life within 50 light years of itself instantly. When it clears away, there's no sign the star existed at all.

I think this is my favorite Crash Course series, I love every episode :)

Each episode
Didn't expect a shred god to grace a Crash Course comments section. Now time to make a shredtastic astronomy song.
My mind gets blown every single episode. WOW.

it's amazing to think that the smallest stars live the longest
This episode was fantastic. I've watched a thousand 1hr long TV documentaries that just show lots of pretty CG graphics and dont really explain the lifecycle of a star all too well. But this episode was perfect and i actually learned ALOT that i hope will stick =D
The fact humans are capable of comprehending this, is just as remarkable as the way the universe works. Incredible.
Getting ready for a test tomorrow on low mass stars, high mass stars, and intermediate mass stars. These vids help so much!
Thank you for this series. Because of it, I checked out a book from the library on astronomy, went to an observatory, and saw Saturn and two of its moons. Never too old to learn.
A trillion years? I can wait.

You WILL wait, no doubt about that.

The fun never ends with this series. Seriously, please never stop doing these, I loved every single one so far :D
High mass star:
Does this planetary nebula make me look fat?
This series can not create new episodes fast enough. I LOVE YOU GUYS SO MUCH!

"stars in the sky look prettyyy"
thanks phil
These videos are one of the best of all of UA-cam! This is awesomely educational, entertaining and easily understandable. Great stuff!!
Literally so more helpful than my professors lectures. Watching these is the only reason why I'm not utterly drowning in AST 105 rn. Thank you!!!
ouuuh! All those teasers, can't wait :D I love this series so much :'D
Loved this episode! The production quality is fantastic, as always, and Phil is a great host. Thanks!!!
*These videos are absolute masterpieces!*
This guy is such a great teacher.

Crash Course Astronomy is so freaking fun to watch
You are so cute in the intro XD
I love your videos, you look so passionate about it you make us want to learn more :) !
Great way to make astronomy interesting again.
Looks like there's 45 high mass stars that didn't like the video.
And its still 46. Somehow.
now 47 :(
Up to 48.

57 now, damn haters
This is such an excellent series. Well done, Phil, et all.

So glad this series exists
This episode was best-in-series for me (so far!)
Wow every time I watch theses videos I learn so much
Phil: Nothing lasts forever
My financial situation: hold my student loan debt
lol
Can't wait to see the upcoming episodes!!
This is my favorite series!
really heart warming hope i can see a red giant in my life time
Welp, if you have a telescope, just point out to the Scorpio constellation. The brightest star, Antares is a red supergiant. Or point it to the Orion constellation, as Betelgeuse is also another Red Supergiant (Which may have aready blown into a supernova )
"Do not go gentle into that good night." That Interstellar reference tho...
+Yoshi's VGM It's actually a Shakespeare reference first and foremost
I LOVE this series. Keep up the fantastic work!
Omg you just saved my grades. Now I can confidently present my report thank you so much☺️
These are the coolest things ever
Saosaq Ii good job here’s an upvote
your videos are so entertaining and informative. i love them all
Love this series iv always been a space geek but you just tell the facts without sugarcoating them

He’s the teacher we all wish we had😩
i will say it again and again space is awesome. and your videos are super awesome
you guys blow my mind with every episode
my vote for the coolest episode so far. Pretty much everything in this one was new to me.
I think this was the most hype episode so far, im not done yet, but omg im so excited
Badass episodes man! Keep up the great work.
Can't wait for the next video about stars. Loving the series.
So basically the sun will turn into a huge diamond? I mean except it will probably be plasma towards the center.. Sounds really cool. I'd like to watch stuff drop onto its surface once it has cooled down. Should be fun :)
you won't see it thats billions of years away from now.
basically yes! There is a white dwarf somewhere which has been named "Lucy" by astronomers. it is a reference to the song by the Beatles "Lucy in the sky with diamonds"
dr edgar But he may see stars like the sun that died a long time ago ;)
Dennis W That may not happen at all.
***** Oh goodie! Not to forget that all our heavier elements came out of a supernova anyway :)
***** Thanks for the refresher. I wasn't sure the term _degenerate matter_ applied here
5:42 - Red stars are soo cool !
Wait if our star is middle aged. What happens when is has a mid life crisis?
it begins a binary system with a star young enough to be his daughter?
schadenfreudebuddha
Lmfao good one did not expect a response like that.
Thomas West I was thinking the same thing
@@schadenfreudebuddha After it buys a motorcycle and grows a mullet... OL J R :)
Though I didn't get it all, this is VERY Interesting!
Thanks for the video.!
Love these episodes! Keep up the great work!
I love this show, I want more! :P
This series is just too awesome. I love this
Thanks for this awesome video, Phil and Crash Course.
"On top of that... Well, there's nothing on top of that" 😂😂😂
Life cycle of the low mass star:
Protostar > K or M type main sequence star > dimmer and darker star > White dwarf star > black dwarf.
Protostar > F or G type main sequence star > Red Giant > Helium Burning giant > Double she'll red giant > Planetary Nebula > white dwarf > black dwarf.
I don't know if I'm more scared that we're gonna get burned by our own sun or more upset that I will never ever live long enough to see it happen.
Phil, you're an absolute star!
Please, never end this series
You're awesome. You explain astronomy very good :)
"Will we go gentle into that good night?" I see what you did there! 😄
one of the best videos yet
@ 2:41 .. Priceless..

I really like this series, and I was wondering if you could make a video each about habitable planets and the search for alien life please. :)

wow this episode sure expanded my knowledge of astronomy
4:38 That Happened With Pure Hydrogen 660 Millon Years Ago So Its Fusing Dueterium
"What happens in the core stays in the core" so the sun is like Vegas?
the most emotional episode of the astronomy crash course
I like this series. They don't take their watchers for ignorant fools. They just give us the facts.
Phil, you are the best.
"will fluctuate wildly over very short time frames" -- Often, when astronomers talk about short time frames it's millions of years. So it would have been good to say what was meant by this phrase in the video.
pretty sure the way he meant it was fairly short time frames for a stellar object
I get so excited when one of these episodes is due - Thursdays are great!
Love these vids Phil!
I think it'll be easy enough to manually alter the orbit of Earth over a span of millions of years if interstellar travel turns out to be impossible.
Entire crash course astronomy is great
Damn tease, I want to know about the bigger stars NOW.
SuperSaiyanMaze You can find out NOW: en.wikipedia.org/wiki/Type_II_supernova
SuperSaiyanMaze A high-mass star is generally one that is roughly twice the mass of the sun and above. They live out their main sequence as stars normally do, but as the hydrogen gets depleted, they start fusing helium into carbon into neon into oxygen into calcium into iron.

Dark Pariah go watch the episode on high mass stars if that's what you want to know
I love the little social reference there when he says "nothing lasts forever". The little guy there
Nice Beginning
Dont go gently into that good night^^
love the reference
