Answer 1

yes. hot gas and no air. so its just a big fire ball basically. That's how we get light. the sun is so hot and bright that even in the winter there is still heat above the clouds.

Yes, the sun is made mostly of hydrogen and helium gases in a state known as plasma, which is a superheated state of matter. The intense heat and pressure at the sun's core cause nuclear fusion reactions that release energy and light.
