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.
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.

This is a list of observed supernova remnants (SNRs) in the Milky Way, as well as galaxies nearby enough to resolve individual nebulae, such as the Large and Small Magellanic Clouds and the Andromeda Galaxy.
NGC 1260 is a member of the Perseus Cluster [6] [3] and forms a tight pair with the galaxy PGC 12230. [3] This galaxy is dominated by a population of many old stars. [7] In 2006, it was home to the second brightest supernova in the observable universe, supernova SN 2006gy. This supernova was the most energetic and brightest supernova on record ...
The estimated mass-loss rates are typically higher than 10 −3 M ☉ per year. There are indications that they originate as stars similar to luminous blue variables with large mass losses before exploding. [34] SN 1998S and SN 2005gl are examples of Type IIn supernovae; SN 2006gy, an extremely energetic supernova, may be another example. [35]
185 – Chinese astronomers become the first to record observations of a supernova, SN 185. 1006 – SN 1006, a magnitude −7.5 supernova in the constellation of Lupus, is observed throughout Asia, the Middle East, and Europe. 1054 – Astronomers in Asia and the Middle East observe SN 1054, the Crab Nebula supernova explosion.
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]
