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 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.

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.

It is thought that SN 2006gy is a likely candidate for a pair-instability supernova. SN 2005ap, which was discovered by Robert Quimby who also discovered SN 2006gy, was about twice as bright as SN 2006gy and about 300 times as bright as a normal type II supernova.

SN 1998S and SN 2005gl are examples of Type IIn supernovae; SN 2006gy, an extremely energetic supernova, may be another example. [35] Some supernovae of type IIn show interactions with the circumstellar medium, which leads to an increased temperature of the cirumstellar dust.
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 ]
