KIDS TRIVIA

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: -Overview: A star is a huge luminous ball of hot gas, mostly hydrogen and helium, held together by gravity. Nuclear reactions in the cores of all stars, including our Sun, produce energy in the form of light. Stars shine because this light works its way to the surface and radiates out into space.

Detailed explanation-3: -Birth of stars and the first elements Within a few hundred million years after the Big Bang, clouds of hydrogen gas condensed into the first stars. In the cores of those stars, intense heat and pressure fused hydrogen atoms to form helium and lithium.
