SN 2006gy was an extremely energetic supernova, also referred to as a hypernova, [4] that was discovered on September 18, 2006. It was first observed by Robert Quimby and P. Mondol, [2] [5] and then studied by several teams of astronomers using facilities that included the Chandra, Lick, and Keck Observatories.
SN 2006X was a Type Ia supernova about 65 million light-years away [1] in Messier 100, a spiral galaxy in the constellation Coma Berenices.The supernova was independently discovered in early February 2006 by Shoji Suzuki of Japan and Marco Migliardi of Italy.
SN 1054 remnant (Crab Nebula)A supernova is an event in which a star destroys itself in an explosion which can briefly become as luminous as an entire galaxy.This list of supernovae of historical significance includes events that were observed prior to the development of photography, and individual events that have been the subject of a scientific paper that contributed to supernova theory.
Thus this category of supernovae has become highly useful as a standard candle for measuring cosmic distances. In 1998, the High-Z Supernova Search and the Supernova Cosmology Project discovered that the most distant Type Ia supernovae appeared dimmer than expected. This has provided evidence that the expansion of the universe may be accelerating.
NASA artist's impression of the explosion of SN 2006gy, a superluminous supernova. A super-luminous supernova (SLSN, plural super luminous supernovae or SLSNe) is a type of stellar explosion with a luminosity 10 or more times higher than that of standard supernovae. [1]
The total energy of typical gamma-ray bursts has been estimated at 3 × 10 44 J, – which is larger than the total energy (10 44 J) of ordinary supernovae (type Ia, Ibc, II), [103] with gamma-ray bursts also being more powerful than the typical supernova. [104] Very bright supernovae have been observed to accompany several of the nearest GRBs ...
SN 2005ap was an extremely energetic type Ic supernova in the galaxy SDSS J130115.12+274327.5. With a peak absolute magnitude of around −22.7, it is the second-brightest superluminous supernova yet recorded, [1] twice as bright as the previous record holder, SN 2006gy, though SN 2005ap was eventually surpassed by ASASSN-15lh.
SN 2006jc was a type Ibn supernova that was detected on October 9, 2006 in the galaxy UGC 4904, which is about 77 million light-years away in the constellation Lynx. [1] [2] It was first seen by Japanese amateur astronomer KÅichi Itagaki, American amateur Tim Puckett, and Italian amateur Roberto Gorelli. [2]
