En '''Hypernova''' kan udsende en [[gammaglimt]] med en ca. 100 gange så høj [[effekt (fysik)|effekt]] som en [[supernova]] i forbindelse med eksplosionen. Hypernova-eksplosionen, der nåede os den [[29. marts]] [[2003]], udsendte en [[effekt (fysik)|effekt]] på 1 million gange [[effekt (fysik)|effekt]]en fra vores [[galakse]]s samlede [[Stjerne (astronomi)|stjerner]].
 
Den [[19. marts]] [[2008]] nåede en hypernova-gammaglimt (GRB 080319B) os fra en afstand af omkring 7,5 milliarder [[lysår]] - hvilket er mere end halvvejs gennem [[universet]].
