GENERAL KNOWLEDGE

Detailed explanation-1: -A star is born when atoms of light elements are squeezed under enough pressure for their nuclei to undergo fusion. All stars are the result of a balance of forces: the force of gravity compresses atoms in interstellar gas until the fusion reactions begin.

Detailed explanation-2: -Stellar nucleosynthesis is the creation (nucleosynthesis) of chemical elements by nuclear fusion reactions within stars.

Detailed explanation-3: -All the elements in the Universe heavier than hydrogen and helium were made in stars through nuclear fusion. When the star dies these elements are then emitted into space. They move into nearby gas clouds, or nebula, and form the building blocks for a new generation of stars.
