What will the Sun become? In 6.5 bil years it will explode to become a white dwarf star (hotter than now, shrink as it used up all of its energy)

Why are the gases glowing? The gases are not, it is due to the heat of the sun that makes it so hot that it glows
-
Are all of the gasses mixed to form the sun? Yes (hydrogen and helium) Or are there seperate layers of gases that form the sun without mixing? No, hydrogen converts to helium and passes through each layer
What colours are other stars? From Earth's atmosphere, inner planets are red/ orange, outer planets are brown and blue
Does smaller things need less gravity from the sun to keep it in orbit? Yes, because they don't need too much hold

-
Why is there solar wind? Sun's electric magnetic field sends it out to the heliosphere but then heliopause deflects it back

-
Why do our skin cells die when there is too much ultraviolet light? The ionised waves affect our cells and that causes our bodies' DNA to change/ mutate which can lead to cancer (applying sunscreen helps).

Why is sunlight bending absorbing all other colors and only allowing us to see red or orange colors? Our atmosphere changes that
Is any part of the Sun rock? (No, it is all gas)

The Sun has six regions: the core, the radiative zone, and the convective zone in the interior; the visible surface, called the photosphere; the chromosphere; and the outermost region, the corona.
