It also had the brightest UVOT afterglow ever recorded once corrected for extinction. [46] It had the largest amount of energy ever recorded in the TeV range, [47] and had the most energetic photons ever recorded for a GRB, peaking at 18 TeV. [25] [20] The burst was ten times brighter than any previous GRB detected by the Swift mission. [48]
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 2016aps (also known as PS16aqy and AT2016aps) is the brightest and most energetic supernova explosion ever recorded. [2] [3] It released more energy than ASASSN-15lh. [4]In addition to the sheer amount of energy released, an unusually large amount of the energy was released in the form of radiation, probably due to the interaction of the supernova ejecta and a previously lost gas shell.

Cassiopeia A is located 11,000 light-years away in the Cassiopeia constellation. A light-year , equivalent to 5.88 trillion miles (9.46 trillion kilometers), is how far a beam of light travels in ...
The solar system might have been hit by the brightest explosion ever seen, scientists have said. The pulse of intense radiation began its life in a cosmic explosion two billion light years away ...
The star is located in a spiral galaxy named NGC 7610, 160 million light-years away in the constellation of Pegasus. [ 37 ] [ 38 ] The supernova SN 2016gkg was detected by amateur astronomer Victor Buso from Rosario , Argentina, on 20 September 2016.
