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.

First long GRB from a binary neutron star merger [11] GRB 221009A: R.A. 19 h 13 m 03.48 s Decl. 19° 46′ 24.6″ z = 0.151: Swift: One of the closest GRB and was the most energetic and brightest GRB ever recorded, deemed the "B.O.A.T.", or Brightest Of All Time. It had 18 TeV, a record. GRB 230307A: Fermi Second only to GRB 221009A in terms ...

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 ...
Earthquake lights may be classified into two different groups based on their time of appearance: (1) preseismic earthquake light, which generally occur a few seconds to up to a few weeks prior to an earthquake, and are generally observed closer to the epicenter and (2) coseismic earthquake light, which can occur either near the epicenter ...
The Sun is the brightest star as viewed from Earth, at −26.78 mag. The second brightest is Sirius at −1.46 mag. For comparison, the brightest non-stellar objects in the Solar System have maximum brightnesses of: the Moon −12.7 mag [1] Venus −4.92 mag; Jupiter −2.94 mag; Mars −2.94 mag; Mercury −2.48 mag; Saturn −0.55 mag [2]
