Hypernova (pl. hypernovae) refers to an exceptionally large star that collapses at the end of its lifespan — for example, a collapsar, or a large supernova. Until the 1990s, it referred specifically to an explosion with an energy of over 100 supernovae (1046 joules); such explosions were proposed to explain the origin of exceptionally bright gamma ray bursts. An extensive sky search found several apparent hypernova remnants, but too few to support the hypothesis
