En Hypernova kan udsende en gammaglimt med en ca. 100 gange så høj effekt som en supernova i forbindelse med eksplosionen. Hypernova-eksplosionen, der nåede os den 29. marts 2003, udsendte en effekt på 1 million gange effekten fra vores galakses samlede 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. [1]

Retrieved March 22, 2008 Citat: "...A powerful stellar explosion detected March 19 by NASA's Swift satellite has shattered the record for the most distant object that could be seen with the naked eye...Several ground-based telescopes saw the afterglow brighten to visual magnitudes between 5 and 6 in the logarithmic magnitude scale used by astronomers...Later that evening, the Very Large Telescope in Chile and the Hobby-Eberly Telescope in Texas measured the burst's redshift at 0.94...GRB 080319B's optical afterglow was 2.5 million times more luminous than the most luminous supernova ever recorded..."
