Supernova explosions

A supernova is a powerful explosion that occurs at the end of a massive star's life cycle. When a star exhausts its nuclear fuel, it can no longer support its own gravity. This leads to a violent collapse and rebound, causing an enormous release of energy. Supernovae outshine entire galaxies and can create impressive cosmic events, scattering elements like carbon and oxygen into space, which are essential for forming planets and life. There are two main types: Type I, which involves a white dwarf, and Type II, which comes from massive stars. Supernovae play a crucial role in the universe's evolution.
