Answer 2

The stars are a hot ball of gases which continuously carry out nuclear fusion process

Our sun is a small medium sized star, so it does not have oxygen but it has only isotopes of hydrogen and helium. Stars glow because of the immense energy produced by the fusion process. It produces heat and light energy. Hydrogen bombs and the sun could be equated they both use the same process to produce huge amounts of energy calculated by E=mc²
