A hypernova is an extremely energetic explosion that occurs at the end of a massive star's life cycle. It is more powerful than a typical supernova and can outshine entire galaxies for a short period. Hypernovae are often associated with the formation of a black hole or a neutron star and are believed to be triggered by the collapse of a star's core. These cosmic events can release vast amounts of energy and produce heavy elements, contributing to the chemical enrichment of the universe. Hypernovae are also linked to gamma-ray bursts, which are intense flashes of gamma radiation that can be detected across vast distances in space.
