Explanation:
Detailed explanation-1: -A star is a huge glowing ball of hot gas. Deep inside its core, hydrogen atoms smash together, forming helium and releasing huge amounts of energy that heats the gas. This is called nuclear fusion, and it’s why a star shines. As the hot gas pushes outward, it opposes the inward pull of gravity.
Detailed explanation-2: -Most stars are made up of mainly two gases, which are hydrogen and helium.
Detailed explanation-3: -Stars are born in nebulas. Nebulas are clouds found in space. They are made of gases and dust. A star’s color tells us how hot or cold it is.
