nucleosynthesis

Nucleosynthesis is the process by which elements are formed in the universe. It primarily occurs in stars, where nuclear fusion combines lighter elements, like hydrogen and helium, into heavier ones, like carbon and oxygen. This process happens during a star's lifecycle, especially in its core or during explosive events like supernovae. The elements created through nucleosynthesis are eventually released into space when stars die, contributing to the formation of new stars, planets, and even life. Understanding nucleosynthesis helps scientists trace the origins of the elements that make up the universe, including those found on Earth.
