Supernova evolution

A supernova is a powerful explosion that occurs at the end of a star's life, typically when a massive star exhausts its nuclear fuel. Without fuel, the star's core collapses under gravity, causing a sudden and intense release of energy. This explosion ejects the star’s outer layers into space, creating a brilliant burst of light that can outshine entire galaxies temporarily. The supernova disperses heavy elements into space, which help form new stars and planets. Ultimately, the remaining core may become a dense neutron star or black hole.
