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]
GRB 200522A is believed to have been formed when two neutron stars collided and exploded, creating an extremely large and bright short-ray gamma burst.The brightness of the emission was 10 times that of predicted, and was around 10,000 times more powerful than the sun in its entire 10 billion year lifetime.

They have been proposed to form a separate class, caused by the collapse of a blue supergiant star, [86] a tidal disruption event [87] [88] or a new-born magnetar. [ 87 ] [ 89 ] Only a small number have been identified to date, their primary characteristic being their gamma ray emission duration.

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 ...
GRB 080319B was a gamma-ray burst (GRB) detected by the Swift satellite at 06:12 UTC on March 19, 2008. The burst set a new record for the farthest object that was observable with the naked eye: [2] it had a peak visual apparent magnitude of 5.7 and remained visible to human eyes for approximately 30 seconds.
