Until the 1990s, hypernovas were classified as such only if they had the energy of 100 supernovas.
In particular, a phenomenon known as a white dwarf hypernova could have sucked alien life into a black hole.
We believe we can operate our Albert supermarkets anywhere in Poland and the Hypernova
hypermarkets in large, but not necessarily the largest towns.
Because supernovas are far more common residents of the celestial zoo than are hypernovas
, this suggests gamma-ray bursts may erupt relatively frequently.
Theorists recently invoked such an explosion, dubbed a hypernova
, to explain the enormous energy unleashed by a gamma-ray burst recorded in December 1997 (SN: 5/9/98, p.
According to a leading theory, a hypernova
jet generates gamma-ray bursts when particles within it collide (SN: 7/10/99, p.
