GENERAL KNOWLEDGE

Detailed explanation-1: -Most stars are made up of mainly two gases, which are hydrogen and helium.

Detailed explanation-2: -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-3: -Basically, stars are big exploding balls of gas, mostly hydrogen and helium. Our nearest star, the Sun, is so hot that the huge amount of hydrogen is undergoing a constant star-wide nuclear reaction, like in a hydrogen bomb.

Detailed explanation-4: -Almost all stars are composed primarily of a gas called hydrogen. The core of a star is very hot. When great pressure compresses it, some of the hydrogen turns into another gas called helium. This process produces an enormous amount of energy and makes the star shine.
