Explanation:
Detailed explanation-1: -Stars are made of very hot gas. This gas is mostly hydrogen and helium, which are the two lightest elements. Stars shine by burning hydrogen into helium in their cores, and later in their lives create heavier elements.
Detailed explanation-2: -Stars everywhere are made of the same stuff: 3/4 hydrogen and 1/4 helium. It’s the stuff left over from the formation of the Universe, and one of the most elegant pieces of evidence to help explain how we’re here today.
