I’ve probably watched your library several times now-I’ve been obsessed with astrophysics and physics In general for a few years now. I build houses during the day and at night I can’t help but watch content like this or especially relevant lectures I find open source. But teaching yourself is difficult to do if you’re unaware of certain things-you don’t know what to look up or what route to take. I find your vids expose me to concepts and niches I wasn’t aware of before and thus I can expand my own knowledge. I’ve got quite extensive knowledge but I believe I’ve plateaued and can’t really progress further until i learn the relevant mathematics. But it’s difficult to know where to start. In any case, “good shit mr Kendall”
Your story about Bart Bok was amazing and proves to me your the the man to go to for great lectures regarding astronomy and science in general. Thank you
When you have such an interest in cosmology you decide to watch undergraduate lecture courses on youtube for fun. Seriously though space fanatics I think we are better off watching this than some of the other youtube channels that span out a microtopic into a 10 minute video with nice visuals but in which you learn next to nothing. Thanks Jason!!!

Thanks for publishing these videos. For the last couple months I’ve been going through them one by one. I noticed you reorganized just recently and was temporarily lost but I figured it out. At any rate, this is great content.
How can extremely low density phases of the MW have so much heat... I was under the idea that you need molecules moving around to produce heat yet the Hot Ionized HII media has extremely low densities.
There's two definitions of "heat," sensible heat & molecular heat. Outer space feels cold to our body & thermometers, but the molecular heat is determined by the speed of individual units. Hence, in the upper atmosphere we have single oxygen atoms (instead of pairs as at the surface) and it's very corrosive due to the high molecular heat = speed of atoms......
It glows as the electron recombines with the hydrogen. Neither is the collision rate so high that atoms cannot stay neutral, nor is the photon field so intense that recombination cannot occur.
Anything's in outerspace with a large enough heavy-lift vehicle. In the case of a woopecker, I think a bat once took a ride on the side of a Space Shuttle booster engine. There's a video, I'm sure somewhere.

Thanks!
BEST astronomy series in the UNIVERSE!!!
Thanks. I appreciate it. Would you be so kind as to share a link or two around?
I love this video! I have always been so fascinated with stars!
Thank you immensely for providing with the most profound and scientifically enlightening elucidation on the subject of star formation.
Your story about Bart Bok was amazing and proves to me your the the man to go to for great lectures regarding astronomy and science in general. Thank you
Thanks Bart was an amazing man. He was someone that I respected and thought the world of.
I'm addicted to these videos 🤩
This is wonderful, thank you for putting it out here.

Good man Jason! Thanks for helping me learn! I think you explain things way better than most people.

Glad to hear it. The correct order is always on my personal website www.JasonKendall.com
8:50 -- Fascinating! ^.^
LHC has density of 100,000 atoms / cc which is about same is ISM
1:11:20 OKAY I'm awake now. Holy crap, it sounded like a nuke went off.
haha this literally just woke me up like WTH WAS THAT? Sounded like a tank or a distorted bolt gun.
I thought T type Brown Dwarfs fused Deuterium for a hundred thousand to a few million years. Is this true?

@@eastockerableand o3 ozone
how can ionized hydrogen glow? there is no electron to change orbits? Or is it the action of the electron being stripped away that glows?
It glows as the electron recombines with the hydrogen. Neither is the collision rate so high that atoms cannot stay neutral, nor is the photon field so intense that recombination cannot occur.
@@JasonKendallAstronomer Thank you kindly!
So when I cut steel with a plasma Arc torch the heat energy is released when plasma phases down into Gas?@@JasonKendallAstronomer
the medium of space and medium of art have the same etymology
Should celebrate a Bart Bok holliday by drawing on big hairy eyebrows, getting a bottle of scotch, and yelling at radio astronomers. = )
Horsehead? That's sasquatch in infrared lo

Thanks for the note. I’ll fix in a remaster.
lol North American nebulae. I wish we had a big old party continent to the east!
are there woodpeckers in outerspace? lol
