The Sun: Crash Course Astronomy #10

Phil takes us for a closer (eye safe!) look at the two-octillion ton star that rules our solar system. We look at the sun's core, plasma, magnetic fields, sunspots, solar flares, coronal mass ejections, and what all of that means for our planet.

As a foreigner and not native English speaker, I really appreciate the loud and clear way you talk. Reading and writing is a thing but I often struggle in understanding natives while they talk. This serie is amazing and so are you, thanks for doing this :)

Phil, you're an excellent host.  They picked the right man.

Love how every subject of CC has the same intro theme, with a little pitch variations and different instruments.

You know I just take the heat of the Sun for granted, especially growing up in Arizona. Of course the Sun is hot, I know that, you know that, we all know that. But it didn't hit me until I watched this how amazing it is that I can feel that heat from so far away. I love that little feeling of realization.

I remember the day I realized the Sun was just another star when I was a child.  It was a mind blowing realization and allowed me to step into a bigger world where I understood not all things I see or experienced were correct.  That there are hidden meanings, connections and explanations that everywhere in the world.

Nice. The other day I was saying, I wish I had a really concise video about The Sun to show my daughter. You guys never fail!

[rosepainter]

Wow... This is why I like Crash Course, because when you are done it just leaves you going "Wow, I didn't know that." Keep up the good work guys!

[iOutSider]

Phil, thank you and everyone at CrashCourse and PBS very much for doing a phenomenal job. I love this show and the whole channel.

Learning about the sun while sitting in warm sunlight makes it special.

The trick to landing on the Sun is to do it at night.

10:26 looks like the Mayans made a slight miscalculation

[nowheregirl]

Phil, you are such an amazing host. Your passion for astronomy shows in your lectures and frankly, I am becoming more and more passionate about this subject myself because of this. Great job!

Such a concise but easily understood explanation. Crash Course Astronomy continuing to be my favorite Crash Course and probably my favorite series on Youtube.

What kind of idiot dislikes these videos? They're among the very best things one can find on YouTube!

[benjaminwilde]

This series is great for passing the time while setting up a communications network in KSP.

CrashCourse, it's partly because of you that I started making videos (in fact, I uploaded my first videos only a couple weeks ago!) in the hopes that I can help people aspire to look at the world through a scientific perspective. And if anyone here is interested in watching more science-based videos, please give my channel a try! I strive to make my videos as visually appealing as possible, and as a grad student who is trying to put himself through school while also supporting his parents, your support and viewership would be greatly appreciated! Thank you guys :D

[eliascastillo]

Thank you for these videos. They’re put together in a educational yet entertaining way. I’ve learned a lot.
