@SW-User Of Galaxy away from point of observation

Without looking up the answers:
2. Wouldn't the gasses have to be burning?
4. A black hole is black because no light can escape it's immense gravitational pull. The light would not be emitted by the black hole.

@SW-User Yeah well. The post was about Star Stuff. So, very pertinent😁

@SW-User The obvious reason for that was so Everyone would
understand😁

@SW-User A Stella Nebula is a cloud of hydrogen, helium, space dust, and plasma.
A Molecular Cloud is a transposable term for a Stella Nebula.
A Black Hole is a region of space having a gravitational field so strong that nothing can escape.
Correct. Black is not a colour. We refer to something as Black when that thing is the perfect absorber of Light
Stars can, and do exist without Planets. They are called Rogue Stars.
This is common Knowledge?

@SW-User Tis so.
A black crayon or marker cap absorbs all colors equally and reflects none, so it looks black to us. While artists consider black a color, scientists do not because black is the absence of all color. All light rays contain color.
So in short, black is a combination of every possible colour contained within the medium🤔 Aight?

@SW-User Well it is here in Tasmania.🤷‍♂️🙂
