What term describes the explosion of a star at the end of its life, releasing a huge amount of energy?

Supernova

A supernova is an impressive astronomical phenomenon that occurs when a star at the end of its life explodes, releasing as much energy in a few weeks as the Sun does over its entire lifetime. This cataclysmic explosion causes the dispersion of heavy elements into space, contributing to the formation of new stars, planets, and even life as we know it. Supernovas are essential for understanding the structure of the universe, as they play a crucial role in cosmic evolution. Their extreme brightness allows astronomers to use them as beacons to measure distances in distant space.
