Galaxies, part 1: Crash Course Astronomy #38

The Milky Way is our neighborhood in the universe. It’s a galaxy and there are many others out there. Galaxies contain gas, dust, and billions of stars or more. They come in four main shapes: elliptical, spiral, peculiar, and irregular. Galaxies can collide, and grow in size by eating each other.

Your last quote, I want to frame that and put it on my wall: "Astronomy is really really good at putting us in our place. But it's also really good at showing us just how grand and awe inspiring that place is" Seriously excellent statement! That sums up why I love astronomy. It can make you feel so small, but at the same time so incredibly lucky and blessed to just be a part of such a breath taking universe. Thanks for the great episode! Looking forward to next week's!

Dang, now I feel small and can't stop thinking about what consciousness is on this tiny rock within one of its billions of organisms. Oh well, back to homework.

when this series end i want crash course paleontology. a science not really talked about and would make for a fascinating series

Regarding to galaxies collision, our own galaxy is on it's "crashcourse ;)" with Andromeda galaxy

[brandonhall]

This is one of the many reasons why I love Astronomy: It helps put things in perspective.

I think this is the best crash course, every episode is awesome!

[faitliv]

Surprised you guys didn't mention that our Milky Way is on a collision course with Andromeda.

Astronomy: the most fun you'll ever have starting at dirt.

[aldisberjoza]

This was one of the most exciting videos on youtube ever. You are a truly good orator.
Thank you for this episode.

[Zwickerly]

I love how these build on each other. Every episode seems to have more references to prior episodes than the last

[MisterDutch]

I should be writing an essay right now, instead I'm watching this. No regrets!

[zahrazatso]

I could totally relate to irregular galaxies, because I, too, am small and chaotically shaped.

[beanny]

I have always felt small when talking about things on the galactic scale, but for some reason, this episode in particular has put me in awe.

[slightlytwistedagain]

Absolutely love this channel for astronomy, presentation is excellent and you don't have the fluff that TV programs have (the sensational dooms day rhetoric or the boring over used "are we really alone in the universe" narration).

I am SO happy when I see crashcourse Astronomy video in my news feed!!

[arandomzoomer]

I think the prettiest picture from space would be the sombrero galaxy.

YOU BROKE MY BRAIN! The numbers, the distances... They cant be imagined by human mind O_O

[phoebeats]

I saw this guy on a different video that talked about galaxies and black holes and I was like "Hey that's the crash course guy." His presence made the video even more liget.

[chaichanaa]

The A LOT thing should really be a meme.

I know I already commented but I have to get this out. This is my favorite subject. I watched the segment with the galaxy collision simulation over and over again. It makes my mind buzz with ideas and questions. Just freaking amazing!
