There's a supermassive black hole at the center of every galaxy, and many of them many host a ton of other interesting objects in their orbits. 0:00-8:40 Planets …...more

Sun-sized terrestrial planets are so cursed

The Galactic Centre situation is crazy

A star surviving its own supernova is badass

the idea of australopithecines having an object in the sky that was darker than the full moon but brighter than any star is kind of unnerving honestly

I like the term "Dust Giant".

Such an interesting video. I always look forward to your stuff. Its nice having a space channel that isn’t just clickbait and actually based in science

Failed supernovae (where the star survives its own supernova then collapses completely) happen closer to around 30 solar masses; the form of direct collapse that happens at a few hundred solar masses doesn't involve a supernova and is actually really interesting - the temperature and luminosity of the core gets so extreme that thermal gamma rays emitted cause photodisintegration of the heavy elements produced by earlier fusion, and being the exact inverse reaction to said fusion, consumes energy instead of releasing it. Basically, the core gets so hot it starts un-fusing stuff, undoing all of the work fusion does to support the star, and as it implodes the rates of photodisintegration only increase further, causing an endothermic chain reaction where the star essentially just spontaneously freezes from the inside out collapsing the entire object into a black hole

I NEED sci fi set here now wtf

Kyplanet893 b is my favorite exoplanet

Who’s up dusting their giants rn

0:23 I find that space basically works with the bodies that are harder to detect and USUALLY less glamorous (dim stars, rogue planets, asteroids) are more common than the famous things that are more detectable.

oh yeah im centering it

I like to believe when good trees die, they go to a planet near 3C273 for everlasting photosynthesis

Just wanted to say how appreciative I am that you take so much time to get these videos out so often. I used to make videos on another channel so I understand how time consuming the process can be. Thank you!!

The Exotic Objects situation is insane.

oh, that render of a supermassive black hole is beautiful.

7:51 this scene reminds me of the view of Miller's Planet in the Gargantua system, as seen from the Endurance Spacecraft from several astronomical units away.

“Dust Giants” How about “Magma Giants” or “Rock Giants”, eh?

In gunbuster, the aliens humanity is fighting evolved on a galactic core planet

4:08 you're actually kinda wrong here. Magnetorotational instability does clump them together. It kinda slows them down and inner particles lose angular momentum to spiral inwards while the outer particles receive that momentum and stretch the disk

imagine ghastly forms of life on these planets that consume vast quantities of rads to survive

I was reading an article on mars and how some are starting to think that an impact similar to how they think our moon formed also happened to mars early on in the solar systems history. So mars had an atmosphere, liquid water on the surface maybe oceans, and at some point there was enough free oxygen in the atmosphere to rust exposed iron deposits hence the red color, which to me says life was there. Our rovers have taken pictures of iron meteorites on the surface of mars that havent rusted in the centuries theyve been sitting on the surface, so whatever was producing the oxygen that rusted all that iron in the past is gone now which again says life was there. But still today we detect seasonal methane blooms, indicative of life, but anaerobic life. We have them here on earth where they form the base of the food chain at hydrothermal vents, theyre also present deepn in the crust and some show up at whale falls in the deep oceans where they consume the inorganic material of the whales skeleton

I'd always thought that if planets forming around big black holes exist, there may also be even metallic brown dwarfs and metallic stars around even larger ones (like TON 618* and Phoenix A*).

Dude your voice has gotten so deep in a year

The rouge planet situation is crazy

looking forward to a habitable black hole planet video!

I love how crazy the universe is and how many different objects and environments it seems to be able to produce, at least theoretically speaking. Every day it seems like our expectations of what our universe is like is rewritten by crazy new discoveries and science papers. Great video!

This is the most exciting interesting thing I learned in a long time. Thank you

I love listening to these while at work.

Seeing another comment reminded me, I and all of us need to thank you for the consistent uploads and high quality!
This would make a sick setting for a sci-fi novel

I'm an astrophysicists studying GC Giant Molecular Clouds -- I don't touch exoplanets in my own work (we're instead interested in the X-ray and broadband outburst history of Sgr A*), but this is quite an interesting video.
Was waiting for this video

All of those objects are son insanely interesting, and there are absolutely no easily digestible info on this subject except your video. Those planets and star types are insanely cool, imagine the world building you could do with that. Imagine if it was added to space engine ! Someone need to make that mod !

Great video

Imagine plate tectonics on such stelar-sized rocky planet.

11:25 it may be out there iron-lead planets as those are the 2 stable elements on the fusion and fission chain

They should rename them to active volatile galactic nuclei so it would be AVGN

LOVE the sound track!
