Stars: Crash Course Astronomy #26

[@58LewisK]

19 years old and I've finally learned the age old question, "Why is the sky blue?" this is amazing

[@tsmsq]

You're a star, Phil.

[@yourfriendlyneighbourhoodh4700]

😂i was looking for this comment

[@thewarlock539]

Oh wow XD

[@benjaminrobinson7203]

No if he was we'd most likely be dead right now.

YazeedSaber what happened to the other guy??

[@blackmesa232323]

The editor did a stellar job. He is definitely the star here. I just wish it wasn't so bright.

[@theunundunly5368]

blackmesa232323 i see what you did there

[@sharanski]

blackmesa232323 his work shines through

[@blackmesa232323]

sharon I bet the office he works in is super hot.

[@sharanski]

blackmesa232323 it must be colored blue

[@Sinnbad21]

I hear he’s a bright guy. He makes these long video in a flash

[@nicjasno]

I could watch Phil talk about astronomy all day long!

[@lolpauve]

nicjasno Well one episode is about 10-15 minutes long so wouldn't it be around 120 episodes for you to be able to watch him all day long? *OR* 60 episodes but you watch them at 0.5x the speed. Damn I'm such a freaking genius. You can thank me later.

[@Oshbotscom]

nicjasno What's weird is that he looks exactly like my old Algebra teacher, but yeah, good stuff.

[@supernenechi]

And I'm actually doing it...

[@eppieeberly7376]

Yea and you wouldn't learn anything, this is way more entertaining than it is informative

[@robadog]

i hate it but ahhhhhh i dont know (i like the video because of it) I'm sorry

[@willemvanechelpoel3336]

the diagram shows how stars die. so it's actually a dieagram?

[@alfredomarquez1916]

So she was named Annie Jump Cannon? Are we sure she wasn't also a superhero?

[@Zerepzerreitug]

or a pirate

[@Master_Therion]

Arturo Gutierrez or a circus performer (shot out of a cannon)

[@andrewdoubleu]

Or the name of a band

[@z-beeblebrox]

Alfredo Marquez Not only is it an awesome name, but it was the product of pure serendipity as well. Her father's last name was Cannon, and her mother's maiden name was Jump.

[@Bird_Dog00]

Alfredo Marquez Whatever she was, she surely jumped the gun...

[@TheMathMog93]

These astronomy videos, are some of the videos on youtube I absolutely look the most forward to! I am getting quite a strong passion for physics and especially astronomy, and these are great to help improve and brush up some of my knowledge on the subjects! Keep it up!

[@paulharris8282]

I'm a truck driver I was just curious the distance of the Sun and the Moon related to the Earth this channel rocks I had to subscribe

[@geniusmp2001]

Without a doubt, one of my favorite topics in astronomy. I can't wait to see all the remaining detail. This is basically the topic about the ultimate ancestors of all life on Earth. And Earth itself.

[@Codiliabra]

I keep coming back to this video! I just adore stars.

[@messionrlfifa6592]

Nah I'm just playin

[@soundslave]

Annie Jump Cannon. Possibly the best name in history.

[@Plunder678]

A year after my degree in Astrophysics these videos are a great way to make sure that I remember some of the keys facts that are a part of this amazing subject! Thank you!

[@K1z0ku]

As a non-native english speaker, I had no idea Betelgeuse is pronounced "Beetle-juice" in english. In my language(Russian) it's pronounced "Betel-gay-ze""

[@TheLightStudios356]

May you spell it is Cyrillic please?

[@K1z0ku]

Бетельгейзе

[@TheLightStudios356]

Hideki Hoshino Спасибо

[@Faarax96]

It's actually an Arabic word,only the Arabic pronounciation is really correct,.

[@K1z0ku]

And how is it pronounced in arabic?

[@shiminshamim8359]

This is seriously my favorite topic in astronomy. And I'm so glad you are making whole series on astronomy. I'm gonna watch it even when I'm on my death bed :) and my friends and family are going to tease me and call me geek/nerd. 

[@prasannanegalur1986]

By far the best series on astronomy on KZbin!!!

[@Shortstuffjo]

I'm just glad to hear there's going to be more episodes! I've been interested in astronomy for well over 10 years now and yet I've learned a bunch from this Crash Course series. Keep making them and make them long!!

[@MilanMilan0000]

red stars are cool

[@MilanMilan0000]

[@keysontrains538]

Nick baker Me too :D

[@NathanAndRose]

I love the representation of female scientists in this video! Yay for women in science! -Rose

[@151daze]

That’s cause they actually did something.

[@KlavierMenn]

Actually, women are quite good at science, when they bother learning. Ada Lovelace and Marie Curie came to my mind!

[@lsaldana7]

Anyone watching this during the 2020 lockdown?

[@Emmacita423]

I'm taking Astronomy 115 as a college freshman, and these videos are how I study for my midterm on Friday! Thanks so much

[@melonlord5711]

These videos are such a big help for my astronomy class. You basically covered all the topics I need to study from my chapter.

[@katyasparkr4431]

this has to be my favorite crashcourse, phil is just awesome you can really sense how much he loves science and astronomy, plus he's such a great narrator and great at explaining everything without dumbing anything down, easily one of the best things i look forward to each week, thanks for all your hard work!

[@williamguru]

Explaining things for surface information lovers. For those who do not concern themselves with in-depth knowledge, this kind of video is very fulfilling.

[@chaohongyang]

A funny tease about Annie: Annie jumped into a cannon and got shot up to near the sun where she discovered that the sun emits different colors than other stars cuase of spectra!

[@acciocake1034]

It's interesting. This comment section seems particulary openminded and polite. I see aggression as a sign of stupidity... Perhaps a lack of empathy/understanding (among humans, obviously.) It seems as though people that enjoy educating themselves and learning are well rounded? Or calmer? So many intelligent, two-sided conversations going on! We all just want to help each other understand so that we can be on the same page and continue talking about what we love! Education reigns! *Sorry if this does not read smoothly, I'm a little rusty at voicing serious sentiments on KZbin, backlash is otherworldly.

[@cyancyborg1477]

Meanwhile, at the religion videos. . . oh my. Much terror.

[@acciocake1034]

Yeah, just got back. Feeling like the world is populated with zombies that scream psalms and molest their siblings.

[@towermoss]

politics and religion are horrible topics.

[@Sinnbad21]

Right on brother!

[@Sinnbad21]

Flat earth and Religion vs Science videos are where you’ll see the worst comment sections. I unfortunately spend a lot of time watching those and therefore scroll through the comments. I’m telling it’s worse than WW3 would be.

[@Rock12402]

Keep teasing as much as you want as long as you keep making videos FOREVER. I love this series sooo much. Great video!

[@lydiaaa5628]

Thank you so much for this series! I'm taking a random astronomy class and you explain things simpler than my professor does! EVERYTHING MAKES SENSE NOW

[@ghania5869]

I got into astronomy at a young age. In senior year, I used to watch astronomy videos everyday. AWESOME CONTENT IN THIS SUBJECT!!! What's even better, crash course makes astronomy even more interesting. Thanks crash course

[@ptl763]

CrashCourse definitely keep including more of the history/methods of astronomy in the episodes! It's making them much more digestible than some of your 'objects of our solar system' videos which had little to none.

[@Zman44444]

1:06 that... sounded crazy with headphones

[@Zerepzerreitug]

"For Science!" XD

[@totalunknown513]

Arturo Gutierrez i laughed pretty hard there XD

[@Corazon806]

I had to pause the video to laugh lol

[@XOsuperior]

"The Astronomical Unit"

[@vatnidd]

I finally understood what Main Sequence meant when I play Spore.

[@jinjukim7713]

This helped me so much to understand stars. I have a sub for science and we only learn from the textbook, which is clear, but I got confused when the sub kept on messing up what she was saying. Even after almost five years this video’s still helping people!!

[@sushilasingh7927]

"Twinkle Twinkle Little Star, oh I know who you are!!" was sparkling , our star Phil.🌟🌟

[@sebastianroundtree1550]

Phil--your limitless passion for Astronomy is ever-appreciated.

[@Shift18]

I always love hearing about all the brilliant women that were such strong forces in earlier astronomy! :3

[@xUniiVerZe]

1. Does the color thingy work for all objects? I understand that if you heat an object up to a certain point, the waves radiated enters the visible spectrum as red. But if you heat it more, will it eventually glow yellow-white, then blue? 2. If stars gain enough temperature, will they eventually emit only UV-light which we cannot see? Same the other way around, will cool stars only emit infrared?

[@George83_Thomas]

Yeah, for the first one stuff like metal will glow and follow the color pattern And he said in the video that all stars emit all wavelengths of light so we would be able to see them, abiet perhaps being very faint like brown dwarfs

[@Doppelganger3D]

I don't know about you guys but this is my favorite KZbin channel

[@Aleinexplains]

Legends seeing this now

[@DeathbyPixels]

Finally! Someone answered “why are there no green stars?”

[@Quark_433]

"On a brighter note,..." No one else catch that? No?

[@robert_wigh]

Thank you very much for making this video, Phil Plait and _CrashCourse_ Astronomy! Yeah, I imagine that this is a very handy tool when obseriving the sky with your telescope, critical to determining what you’re seeing. Thanks! I do have the same question as I had last time we talked about this topic: what if the light emitted is compensated by the temperature of the star? How do you tell the difference between a very hot star far away and a cool star close nearby? Will they look the same? I know, you could of course tell by the size but I imagine that would also be compensated by the distance.

[@tiny_M]

*hand waves* Triiiiiiiiigonooooometryyy. (Which is a very very simplified way of summing up a whole bunch of math and physics! It confuses me too, but this is a decent looking page on Stack Exchange that might help, if I understand your question correctly?)

[@garethdean6382]

Stars have always been a hot topic, a real gas. You can bet I'm giving this video a glowing review.

[@Elephantine999]

I can't believe that I'm just running into this for the first time. This is a great series.

[@SaraAnneMiller]

I look forward to this series every week!

[@uzundeprem5743]

Don't ever end this series!!

[@starexpander8759]

well the intro isn't creepy or anything

[@RastaPilot737]

Tanki36 ask Isaac Clarke

[@liamdoyle5363]

I thought it was rather profound actually, it's almost like the human desire for knowledge, to the point that we actually challenge the universe

[@DanThePropMan]

"Jump Cannon" is easily the second-most badass name I've ever heard. It doesn't even sound real!

[@everbiage7745]

watching the series a second time, about a year down the road. Amazed at how much I'd missed the first time around. Definitely worth re-watching (at least for me :) )

[@shygirl7782]

He is just amazing. Make things super easy.

[@tatioliveira8598]

I wish Crash Course Astronomy never ends!

I hope we get another 26 episodes in this series.

[@brianna5993]

Your awesome Phil! Ty for all you do; I've home schooled for two years and this was my first year using you! I wish I found this sooner. WOW your awesome! I've always loved astronomy; but now i love it even more!!!! thank you for all you do I appreciate you soooo much! THANK YOU PHIL!!!!!! Sincerely, Brianna :)

[@alamri1121]

this crash course better be at least 100 episode!!

[@Joe.gepitulann]

You are the best. I love learning from you because you have the best teaching style for me so when I grow up I have more experience of how astronomy works because of your amazing teaching.

[@spaceenthusiasts8725]

*_What a thumbnails you pick for you videos, amazing... Wonderful thumbnails_*

[@coneyislandqveen]

i'm literally watching these videos on repeat tryna cram for my cosmos final tomorrow. this is so helpful

[@Mystik3eb]

Will you guys talk about star-quakes at all? I've heard that they can be in the thousands or even millions or higher on the Richter scale, and that just...blows my mind.

[@nanawav]

The intro got me hooked I already like this guy !

[@AntDoesStuff_]

6:42 luminosity and temp (Its the reason why im here so i thought it might help u guys)

Love having breakfast in front of crashcourse, dunno why :p

[@RenneMeejahUnfiltered]

Great crash course. Very clear and articulate.

[@dmitryr9613]

Wow, this was an incredibly informative video, probably the most informative 10-minute video I have ever seen! It helped me understand a whole chapter for my science test, I couldn't thank you enough for making this video.

[@Alejandro-SM]

CrashCourse How about an episode dedicated to planets similar to Earth, like the newly discovered Kepler-452b? and how much can we learn from this planet just by looking at it?

[@jonhoolio]

coming in clutch for my astro final tomorrow.

[@DJAIV]

Wtf happened to the exoplanet episode?

[@crashcourse]

Dexter Armstrong We overlooked an error in the segment on reflexive motion that proved too large to simply annotate, so we decided to pull the episode to correct it. Unfortunately now everyone has to wait an extra week for all that exoplanet goodness. SOON, FRIENDS. Soon. -Nicole

[@glitchxero4687]

It's nice to see Jeb, Bill, and Bob there on the desk.

[@CuriouserProductions]

I have been wondering why there are no green stars ever since we started learning about Astronomy earlier this year. I didn't expect you to answer my question, but behold! It's like you can read my mind :O

[@ruparkyitin]

Because there is no existence of green color wavelength photons or particles.

[@CuriouserProductions]

+Rupar Kyi Tin did you watch the video?

[@hellfirethebeast814]

What if we had a blue star as our sun? What would the earth be like? What would life be like if we were in the star's habitable zone? How would the planets be different if Jupiter was a sun? What would be different about the earth if we had two suns, besides perpetual double shadows? Just some of the star questions I have. Sorry if they're stupid.
