19 years old and I've finally learned the age old question, "Why is the sky blue?" this is amazing
-
You're a star, Phil.
-
The editor did a stellar job. He is definitely the star here. I just wish it wasn't so bright.
-
the diagram shows how stars die. so it's actually a dieagram?
-
I could watch Phil talk about astronomy all day long!
-
The intro was so freaking creepy! "Oh... I know who you are..."
-
OBAFGKM: Only Bad Astronomers Forget Generally Known Mnemonics.
-
Annie Jump Cannon. Possibly the best name in history.
-
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.
-
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!
-
So she was named Annie Jump Cannon? Are we sure she wasn't also a superhero?
-
Anyone watching this during the 2020 lockdown?
-
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.
-
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""
-
I keep coming back to this video! I just adore stars.
-
I love those Kerbals on his table XD
-
"There are no green stars. Look as hard as you want, and you won't find any." -Me in Super Mario Galaxy 2
-
"On a brighter note,..." No one else catch that? No?
-
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!
-
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!!
