A supernova is a powerful and luminous explosion of a star that occurs either during the final stages of a massive star's life or when a white dwarf undergoes runaway nuclear fusion. These explosions are so bright that their peak light can rival an entire galaxy, making them important markers for studying the universe, though the original star is either transformed into a neutron star or black hole, or destroyed entirely.
