who just decided to start studying space like me?
Anyone in 2024?
Me: [starts the astronomy playlist] This is big brain time
Agent J-23-1991 ll
Dawg I got my astro final in like a week, this playlist is gonna save my hide
True
his 'astronomy puts you in place speech' intensified my existential crisis
+diannesider Existential crises suck :(
😂😂😂
Anyone know of a good video that shows things as seen by the naked eye and then zooms into it really close? I would love to see that but cant find anything like it
Who ever makes this 334 likes is very sad
"Understanding that our understanding might be wrong is essential, and trying to figure out the ways we may be mistaken is the only way that science can help us find our way to the truth."
My, that's deep.
Phil's full of brilliant gems of wisdom like this. There's a lot of great stuff coming up in this series. :)
-Nicole
I like that though. We know has much we know, and, we must be ready to accept that we now know, is wrong and need to change.
mestre12 Well it's the basic fundamentals of science. Theories are not things that remain static and absolute once we find evidence for them. They aren't ever a thing you "Prove true" they're just something we have yet ot prove wrong or improve upon.
***** Fuck off you misogyinist piece of shit
HugsmadeDrugs Ignorance should never be something to be looked down upon for. How can a person be at fault for not knowing this state of mind? But there are quite a number of people that do not know this, even a great deal that "side" with science. In our education systems, we teach science as if it was fact; hardly ever is the actual fuzziness brought up or the possibility of new knowledge replacing ever brought up. Even in the scholarly community, many researchers and professors could do with relearning this basic tenant of science. When something knew comes up that could replace old thought, huge amounts of backlash from the scientific community can come forth. Take the recent discovery of possible arsenic-based microbes, there were large amounts of backlash to the researchers conducting such things.
Ignorance is just part of the human condition. The job of science is to try to lessen it.
I want to be an astronomer when I grow up. I'm not sure if that means writing books, or teaching a class, or working in an observatory, but I just want to be able to learn about the universe and then teach it to other people. I'm not sure if I'll actually be able to DO that, but I'll just have to see how life goes and learn what I can for now. Thanks for this Crash Course!
+Alexandra Rodriguez It means/can mean all those things. Surely, you will write, because in order to be an astronomer or astrophysics by an university, you need to do a thesis -write it down.
+Captain Sum Ting Wong Well good luck. Im 13 and hopefully able to be an Astronomer but for that i'll have to improve on my maths.
Only been one year, but I would hope you're still going at it.
Unless you found something you enjoy even more of course.
Alexandra Rodriguez go for it! Good luck and do your best 😊
me toooooo
I started crying in the end
I don't know why, but it's so touching
I love knowledge, I love science
I love learning about new things and the world
It's just so fascinating😭
It's ok to 😢
Yep
As a kid in a country like Afghanistan it's been always a big dream of mine to learn about the cosmos and become an astronomer. I remember every summer night which I was sleeping outside on the balcony, I was staring at the sky for hours and I was amazed (and still I am) by the world up there.
As the time went on and I grew up, specially in the last years of my school I realised that in order to make a living for myself and for my family I've to study sth. which I could find a job in the future in a country like Afghanistan. So I decided to Study Civil Engineering; right now I'm doing my postgraduate studies in Civil Engineering in Germany. But still I couldn't forget about my dream and even today astronomy is my passion and who knows may be this video was a kick off to start with it. And I'm sure I am going to start learning about the universe seriously.
one day.....
"the fault in astrology lies within ourselves and not in our stars" I see what you did there. Clever
Cotton Candy Tory That’s à quote not famous from the book
Who told u child. Try to read ancient books on Greek and Thamizh literature. Most of our ancients believe that. Only we people are disparted from that theory
Actually john gree books name is fault in our star ssssooooo
@Irritable Jon Syndrome a quote from Shakespeare's Julius Ceasar... "The fault, dear Brutus, is not in our stars. But in ourselves, that we are underlings."
Google, the Northern Cross, by Aquilla Fleetwood, youtube!
Why is crash course so good? Everything from the speed of speech to the music background to the pleasant animations...How many geniuses did it take get with this perfect formula?
1:35 the mitochondria is the powerhouse of the cell
Are*
Oh god
Yes, with oxygen you create energy.
Big brain time
I like the pace of your speech. New subscriber. Thanks!
three minutes in and the existential crisis strikes
+Padma Venkat Yes Dan should never watch this video
Gabi W. Ikr!
I get my existential crises from the stupidity of humanity. Science is an escape from my fellow human morons.
+theuncalledfor I get you on a personal level.
Padma Venkat oh hi
This dude's voice is so awesome it's now going to replace my brain's narration voice, so I can hear him explain everything I do.
"ManToast, feeling more creative today than usual, decided to combine his coffee with the hot chocolate he forgot he kept in the back of his cupboard, thus creating a mediocre, yet still satisfying, Mocha coffee."
It's not weird, I promise.
Diana Peña i have 2 inner narrators, when i'm doing something i find interesting, it's Morgan Freeman, when i'm doing something boring, it's Mike Rowe.
kollin thompson Mine is Cecil Baldwin, but hey, you like what you like.
Yea. This guy and Morgan Freeman are going to have to duke it out as my brain narrator.
He's my new inner narrator as well. This voice isnt too exciting, but isnt too calm either. Like the third bowl of porridge, its just right!
I can leave that as a voice message on your phone.
Shoutout to JohnGreen the author of the book "The Fault In Our Stars."
"The fault of astrology lies in ourselves, not in our stars."
Hahaha
I’m 17 and I’m taking an astronomy class at a junior college this semester and I’m so scared 😭 it’s basically quantum physics of space
1GirlOnFire1 I’m watching this for cub scouts and I understand everything.....
Sorry if I sound rude...
Bro quantum physics is worseeeeeeeee
@@dhadkandewan2664 well actually no if you do it with passion
@@dhadkandewan2664 but yes... No one understands quantum physics.
I demand MOAR of this, NAO! By that I mean, thank you so much for doing this.. for free, you guys are awesome!
Soon! Soon!
-Nicole
CrashCourse yesyes
CrashCourse where is green
Support them on Subbable! (:
Ethen Sun Randomness I would say "where are greens" I'm ok with either of them.
I love the Millennium Falcon on the desk. (And the set in general.)
Thanks. I agonized over it for months before we actually built and hung lights. I'm glad people seem to like it.
thelonelydirector
It's awesome.
Isn't the the same falcon Hank Green and Michael Aranda built a while ago?
Swiftflight Good eye, :)
That was the first thing I noticed on the set. And it's AWESOME! I have that kit it's pretty great! They should add a Star Trek model too ( it would have to be an amt model since that's all that exist) there is room for both right? Right?
Oh yes big daddy astronomy, put me in my place
c'mon! I just got off tumblr now I have to kinkshame someone on youtube, too?
dafuq Nice Meme -.-
hahahahahaha i love you, whoever you are
Lmao
bahahaa @nice meme
I wanna be an Astronomer !
EmperorMartin good luck pls never give up we need more people you may even one day revolutionize us humand
EGA Trickz me too! I love space.Its so cool.
EmperorMartin Me too! I'm thinking of starting a club at school!
Wow,this really makes me put Faith back into Humanity :D
***** Still better than Hillary imo.Both are Shitheads tho.
So excited for these new Crash Course themes - ya'll are awesome :o) Well done on the first episode - you have me hooked!
We love them too! ***** did a fantastic job - we flailed a little in the office when we first heard them.
-Nicole
+CrashCourse Hey guys! I really love Crash Course and know that Crash Course Astronomy is over now, but if you could PLEASE PLEASE PLEASE PLEASE PLEASE PLEASE PLEASE PLEASE have Neil DeGrase Tyson if you could. Thanks So much for all you do! DFTBA!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
+CrashCourse thanks your video really helped me I got a A+ on my test because u explan it really well😃
Hahaha
Расиия свещенная наша держава
I'm actually really looking forward to this. :]
deoxys confirmed and please more sunscribers ffa
Wait....Nappy?
The last place I thought I'd see you...
Lol me too bro
I love astronomy too, but I would love if they start talking about philosophy.
I love learning new life lessons. Hooray
That is good
subscribe me please
Me too
Ok
U are helping me to be astrophysicist thanks alot will always remember you
F*CK YEAH! Crash Course Astronomy! One of my favorite sciences!
Wait.. where's Hank? or John?
Calm down kid, they aren't experts in everything
Phil Plait is AWESOME!
Phil Plait is a much better choice for this, he's a badass. Oh and he's a professional astronomer.
To be honest I think he's a lot better for this, it's a lot more relaxed and calm than Hank's science videos and he is somewhat better informed on the subject.
I quite like the way Hank and John are more... Energetic? I don't really know what the right word it, but Phil is much more qualified to be teaching this than Hank and obviously more than John (no offense John, but science isn't particularly your domain.)
Sometimes I think humans still know nothing and that since we can't fathom many things we must not be very intelligent in the grand scheme of things, but then I look at how much we do know and I am astonished and blown away by my own species...
Let me correct you by saying the majority knows nothing, check out pbs space time for starters
Nat Cat islam is the way, islam explains these but west never shows
"Rather you know it or not, youre soaking in science"
Im in the bath watching this, that spooked me
0:10
This is the best Crash Course opening ever.
This is shaping up to be my favorite crash course series right behind big history.
I still have nightmares about the futurism episode: the end of matter...
juampan Imagine if it could be stopped by science....
Well, we have a couple trillion years ahead so, let's hope so.
yup.
TheSignetGamer insufficient data for meaningful answer
Awesome presentation. I can only hope Neil DeGrasse Tyson makes a guest appearance in future episodes. Phil Plait does an absolutely outstanding job presenting here. The pacing felt just right. I would love to just listen to a conversation between Neil and Phil.
***** do you mean Star Talk or something else?
***** wicked, thanks for letting me know about it.
Oh please can't we just speak astronomy without him for a change?
I love Neil as much as the next fangirl, but he is not the embodiment of astronomy. ;)
samtron5000 yup true...I think same about that.....
This is an amazing Astronomy guide, and the quality of the entire thing is obviously top notch.
I'm a geologist and at 1:44 when you say the Earth is mostly molten rock and metal, I have to clarify that there is very little molten rock in terms of volume of the whole planet. Magma is only formed near the surface where the pressure is low enough to allow it to expand into a liquid. But it's also exposed to the coldness of Space, so it becomes solid relatively quickly.
I have seen this misconception before so I thought I would mention it for anyone who would find it useful :)
I can't believe this was *four years ago.* I remember being so excited for every episode of this series.
Astronomy is awesome, it tells everyone something we all need to hear; "You are small, you are next to to nothing compared to the universe. Finally, you, and all of your actions and choices, are incredibly, extremely, _exceedingly_, Important! Everything you do changes the universe." We'd do best not to forget that.
"It has been said that astronomy is humbling, and character building experience..."
-Carl Sagan, The Pale Blue Dot.
First thing that came in my mind: 'is this the guy on Discovery?' (on 'How The Universe Works) lol
I had to look him up and I'm kinda sad i didn't do that before, so I could find this channel earlier as well. He seems to explain everything in a way that makes it easy to understand and remember
Savage John Green reference is savage.
it existed before Jhon Green
max rin you sound like CinemaSins when you said that... Lol
I'm an amateur astronomer and I've been waiting for this series since however many months ago Hank mentioned it. I haven't watched the video yet but I'm really holding out hope that this series is decent. I know Phil Plait well, and if my word means anything, give him a chance. Just because he isn't one of two people in the entire world who you'd be happy hosting this series, doesn't mean he wont do an awesome job.. I'm sure. *Starts video*....
What? does not compute. How did anyone watch this and think man screw that guy, I want Hank! or I want John. They're both epic and all, but If the option is there, I'd (and apparently so would everyone at Crash Course) rather someone who legitimately knows and works in the field their talking about. When they started CC they didn't know it was going to be PBS sponsored, or that it was going to branch off so much. Of course they're going to hire people to talk about what they know. How doesn't that make sense? Big, massive thumbs up to everyone at CC, and i'm only 5 minutes in..
"Amateur astronomer". *KSP for a profile picture.* Hmmm...
Imad Gibbs Yes! :D I'm both an amateur astronomer and a.... um, professional Astrophysicist (frankly less good at former than the latter, actually :P), and I can only agree with you
I'm an astronomer in the sense that I play KSP. In other words, not at all.
Good to see fellow Kerbalnauts.
Anyone else watching again since it just ended? I'm gonna miss these every week :(
+20buckman12 :(((
+20buckman12 IT ENDED!?@?!? i just found them :(
xBluR Plays Don't worry,there's 50 episodes and they're all great. And I should say they finished it, ended may imply that it got cancelled or something.
+20buckman12 Thank you. I shall complete Crash Courses Astronomy playlist!
+20buckman12 Just started watching for the first time :))) so excited
You just would not believe how many time I watched the entire serie, over 20 time. THank you so much for gathering so much info, and narrating it so well
I'm pumped, ready to learn the stars ⭐
OHHHH NEWTON. . . . .
Found it.
no
Empty spot on the top-right shelf!
I vote for a picture of Earthrise. (if it's not too small)
everyone in favor say aye
aye
aye
Aye!

Minecraft Jayy i see waht you did thare
That Fault in Our Stars joke was too good
Phew, looks like I'm only 3 years late to the party :D
From a cosmic standpoint, just a blink.
This course should win public prize!
I'm sorry, but I can't watch this video. The title alone damaged my brain's hype center, and I'm afraid that actually watching the video might kill me, by overloading my awesomeness receptors.
whats wrong with the title.
Mr Barwick He's saying the video's too awesome. Seriously you didn't understand it?
Topaz Emerald it went right over my head. haha
Oh, man, I knew I forgot something - the official Crash Course Astronomy Warning: MAY OVERLOAD AWESOMENESS RECEPTORS. ;)
-Nicole
CrashCourse So, a member of the CrashCourse crew just replied to my comment... Well, there goes my awesomeness receptors, again! :)
This may be weird, but I *love* the brief opening animation and theme song for this series. It communicates the wonder and joy of astronomy so succinctly.
"the answer to the universe and everything is... 42!"
the application of sci-fi references in science classes amuses me very much
I never hated anything more than hearing people saying that I am majoring in Astrology.. One of my mom's friends wanted me to do fortune telling to them and after me saying that i can't she told me that I am bad at my job and I am not going to be able to find a husband lol..
lmao fucking idiots
+Alper Korkmaz I HATE THIS SO MUCH. I know people mean to say Astonomy but it's such a pet peeve when they say Astrology ahhh
What a horrible friend.
+Rosie Tilbrook In my honest opinion, astronomy should try to highjack the name astrology back to its strictu sensu meaning. This, in turn, would help to distance pseudo-scientific BS from it even further, as now-astrology would have to find a new name that shouldn't be anything close to the original.
If I'm not wrong, there ARE people trying to redeem the swastika and the toothbrush moustache (famously worn by A. Hitler)... so it's something to think about? Maybe?
+Alex Schrijnemaekers I think astrologers would stubbornly hold onto the same, and try to conflate their ideas with science. Wouldn't discarding the distinct word we have now (astronomy) create confusion?
This is so great. First time I watch someone talking at the speed of light but getting all the info across in a very lucid way.
trueeeeeee
This is so well produced!. Sound Quality, Video Quality, Graphic Quality - Just perfect.... But Phil did the most wonderful work of putting the content across so well; bringing the content alive and engaging. PBS studios you are lighting that essential spark of curiosity in the minds of a viewer and sustaining it for a packed narration for 12 minutes... you have a skill which is very rare and very much in need throughout the world.
This is seriously the best series of videos on the internet. This series should be on Netflix, absolutely awesome, clear concise information, and passionate delivery. 5 stars dude (pardon the pun)
Re-starting this playlist again, I love it so much 😍
The fault in our stars reference killed me 😂
Came here because i feel dumb understanding the black hole thing. Starting with the basics haha
(I'm totally late)
Don't feel dumb, not everyone immediately understands everything we're supposed to learn. Just be confident, and allow yourself to work harder on what you don't clearly understand!
(Btw sorry if this comment is completely irrelevant)
no one is too dumb. trust me...if you really want to understand something you will
Phil PLate :"Ill be taking you on a guided..."
ME:"...Meditation?!..."
Him:"...tour of astronomy"...
Me:"Oh...straight to stars!"
Is this where the Kardashians live?
Ajakskss
I just love how happy Phil looks in the opening because he has these huge grins on his face, and I know anyone who loves the cosmos gets that same grin whenever space is even mentioned. Great series!
I write comments about anything very rarely, but this series moved me to do just that. It's really one of the best videos I saw in the whole time, including not only TH-cam, but TV and shows as well, and I'm surprised that it's not getting as much views as it deserves. It explained to me a lot of things about astronomy I didn't quite understood before, though English is not my native language. I will definitely recommend this series to anyone who is able to watch it.
You should compile all these courses in one book and publish them it would help a lot too btw you are doing an amazing job I'm glad I found this channel thanks a million
I've recently gotten into astronomy and this series is gonna help me soo much, I'm sure! Very excited to see all the videos. I'm only a minute and a half in and already hooked!
It's been a year now, and I've grown so attached to this series I already miss it. So sad that the it had to end
Crash Course is produced by PBS now, wow. Great work, folks.
this is easily the best crash course series... no the best complexly series hands down. I have to watch this at least once a year
Truly mindblowing, and it just keep getting more so for every episode - love it! Without doubt THE most interesting and most well explained videos on the subject that I've seen ! Great work and thanks!
A year to the day since this series started! The best one since Crash Course World History IMO.
Today I started watching from the very beginning and taking notes! I am really enjoying myself while doing this! thank you!!!!!!
that's what i do
Carlos Maldonado Me too :) I'm planning to write the points of every single episode in my notebook like I'm taking real Astronomy class!
these videos are really fun .
This is the first time I've gotten interested in astronomy and I like it. 😊
I'm so happy you guys are expanding your subject list. Everytime I start a new class in college I always look to see if Crash Course has added the subject yet. I watch the videos that corresponds to my lessons and get better grades. Thank you guys so much!
Thank you so much! Greetings from Egypt! 🇪🇬♥️
This looks so fun! Excited for the other episodes! Love Phil's enthusiasm!
I'm studying environment at the moment, and I have to take geology. I love learning about the world and geophysics, and now I want to learn astrophysics and programming, and how to code all those things, it's all so interesting
The only problem is trying to learn them all, but I'm determined :)
Your gorgeous
Good for you! keep up the good work and your curiosity
Ay programming is very difficult at first, if you're good at troubleshooting then later on coding is pretty easy. And knowing a coding language is almost always useful
Agreed , not only that but being able to program is a very good job to do, a lot of people always looking for reliable programmers
"You might want to pack a lunch", me: probably 47 lunches
this should be mandatory watching for all school kids
I know of this man, now he is in a thing that I love, therefore I am happy!
I have just recently come across your channel & I cant began to tell you how perfect & relevant I find this, especially for people who have an interest to learn & understand. I do not have a science or astronomy background, but I have always been so interested in astronomy that I go through video after video on you tube that might give me any related information. But these videos are random selections & they give you just pockets of information.
Your videos give a synopsis of a select subject within astronomy. Thank you so much for this information & the way its thought about & presented for general understanding. You made my search worthwhile.
I’m 12, but I was bored studying biochemistry, prosthetics, DNA and disease, so I decided I wanted to learn some astronomy. Thanks for this series!
Every time i see pics of galaxies in the universe i get so mindboggled and think i can't even imagine idea of just how small we really.
Fantastic series, Phil. Thanks and keep up the excellent work!
It sounds like an awesome series! Looking forward to seeing it all. Thank you very much, CrashCourse, for creating this series and especially thanks to you, Phil Plait, for hosting.
This is my dream when I was a kid. But due of financial problem way back. I'm unable to take this Course ending up as an IT. That's why I'm thankful to this video. Atleast my dream come true :) . Thank you. Worth to subscribe to your channel!.
As a child, astronomy was (and still is) my passion. I still want to learn more, and while I did stray off for a while, I find my way back to the heavens.
Well done, Phil! Happy to help share this around. Thanks for including great input about light pollution, too.
I cant believe this!!! Crash course Astronomy!!! THANK YOU SO MUCH GUYS!!!! AND FOR ALL THE LATEST COURSES
Crash Course is amazing because, while other courses teach from a perspective of the universe looking down, Crash Course starts from an Earth perspective, and then focuses your eyes upwards on the universe.
This is amazing! I wish more people would watch this, we all need to learn this!
This is incredible quality educational content! I'm blown away that it's available for free on the internet. I look forward to watching and re-watching all of these episodes for myself and sharing them with my future children (if I choose to have any). What an exciting time to be alive :)
Liked after five seconds at "I'm your host Phil Plait."
Passed my General Astronomy university course with help from this series :)) Thank you CrashCourse, thank you Phil!
This is an amazingly well written and produced video. Thank you very much!
This is beautiful. I study Visual Arts (filmmaking) but I LOoOOoOoVE Astronomy and science and my heart wants to learn more, so.. I LOVED this channel, CrashCourse it's just so beautiful, thank you all for making this. I am learning so much hehehehe.
I got excited, lol. Thanks guys. God bless your souls UuU
***** and thanks for the spanish subtitles
Whoa, everyone, chill. There are other intellectual humans out there besides John and Hank.
So excited to rewatch this! Phil is my favorite host on Crash Course and this is my favorite series (though I haven't seen Hank's Chemistry or Psychology series, yet).
The field of astronomy is so intriguing that everybody wants to know something about it. I have always loved to know more about astronomy.
Thank you so much for this series!! crash course, singlehandedly, is responsible for me passing for astrophysics exam. You guys are the best!
I love to learn about astronomy soo much so thank you for teaching us and I hope that this series will continu! 😊
I love these videos. I'm using them this year with my Earth Science Class. Fantastic content!
I love having people explain all this to me! It’s makes me feel smarter!
I really enjoyed the video and I am planning on watching the rest of the series. Also, this field of science is actually something I want to take seriously in my career path (as I want to be a physicist of some sort I haven't work out the details) and I am glad to get a good source for learning about this awesome reality that I am a part of, outside of school. Thanks again for the video and keep up the good work.
Excited to see how this progresses. I am looking forward to learning more with Mr. Phil, even though it's weird hearing someone else other than the Green Bro's on this channel.
This video was so inspirational! I'm definitely gonna watch the rest of these. I took Astronomy in college and I LOVED IT! I also graduated with a degree in computer science and math. I do really enjoy programming, and I'm hoping I can get my leg into the astronomy field. Any ideas where to start?
Crash Course just explains everything so well, and I can actually hear every word they are saying (they don't rush). Thank God for Crash Course!
