The atmosphere of Neptune is really 50% hydrogen,30% helium and 20% methane.
it is primirly composed of helium and hydrodren along with traces of methane
The same ones that are outside a black hole: Mostly hydrogen, some helium, a smattering of other stuff.
hydrogen and helium gasses and any other stuff the star had in it.
Most stars consist mainly of hydrogen and helium. However, they also have smaller amounts of the so-called "metals", i.e., heavier elements.
Mostly hydrogen.
star or nebula
Uranus was formed from the light gases of the outer solar nebula.
Nothing can be on a nebula. A nebula is gases and plasma. It is where stars are produced. So nothing is on the Dumbbell nebula. because the elephant sat on your mom. LOL
A nebula is a cloud of substances and gases that can form into a star. A star is a ball of hydrogen and helium with trace amounts of other gases. A supernova is the death of a star.

Nebula is an interstellar cloud of dust,hydrogen, helium and other ionized gases.

Hydrogen and Helium gases make up the universe.
