Brilliant Reporting! Thank you!

Awesome stuff Chris! Such stunning views

Great videos Chris 👍👍👍

Just subbed. Enjoy these explanations & images. ✨️

DAAAAANG!

Interesting video. You should give measurements to these objects.

2:20 A stupid question I suppose but where do Brown Dwarfs get their surface temerature from? As for the rest, well you just blew my mind! 🙂

Primordial heat from the material falling in, decay of any heavy radioactive elements, and the fusion of deuterium. There is some fusion in brown dwarfs, just not hydrogen fusion.

From the gravitational potential energy, of all the gas that collapses from a large cloud into a sphere (the brown dwarf.) If you drop anything here on Earth, for example, the gravitational potential energy becomes kinetic energy (which is heat.) You can try examples at home to illustrate that heat is just random kinetic energy: go hammer a penny and see how it heats up.

One question--are Brown Dwarfs static, or are they able to continue accumulating gas to some day become a star?

It was known that Brown Dwarves are the death of small stars as well. It was in a other older video. Now if they collide together who knows.

I suspect that the data & images from JWST will revolutionize Cosmology. "The Infrared Catastrophe", perhaps?

I envision someday a desperate advanced civilization combining brown dwarfs to make new stars

Why necessarily a desperate civilization? If sufficiently (and scarily) advanced, it may merely be the subject of an astrophysics project.

@howardrisby9621 my thought was in the way distant future, when all the available stars are about to be exhausted, the combined dwarfs would be new stars for billions of more years of living.

Your chart showed that gas giant planets can be up to approx 13x the mass of Jupiter, before they become classified as brown dwarfs at roughly between 13x to 80x the mass of Jupiter. But then you said that these brown dwarfs have less than 8x Jupiter’s mass, with the smallest having about 3x Jupiter’s mass, so I’m guessing that a gas giant size body, is considered a brown dwarf if it is not orbiting a star, even if it has less than 13x Jupiter’s mass?

OK, I looked it up, and aside from whether or not it’s orbiting a star there are other factors, such as how the body formed, it’s “metalicity” (as described by Anton Petrov in his gas giant vs brown dwarf KZread video), and probably some other variables as well, in determining the body’s classification. I think I get it now.😁
