A supernova is a powerful and luminous explosion that occurs when a star exhausts Its nuclear fuel and collapses under its own gravitational pull. During the explosion, the star releases a tremendous amount of energy, emitting a bright flash of light And producing heavy elements that are scattered throughout the universe.

Supernovas are some of the most energetic events in the cosmos and can briefly Outshine entire galaxies.

They are also important for the evolution of the universe, as they help to distribute elements necessary for the formation of planets, stars, and life.
