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.

Hawaii – Southern: 7.9: X: 31–77: Limited damage / homes destroyed / tsunami: Note: The inclusion criteria for adding events are based on WikiProject Earthquakes' notability guideline that was developed for stand-alone articles. The principles described also apply to lists.
In the summer of 1996, a swarm of 4,070 earthquakes was recorded at Kamaʻehuakanaloa. At the time this was the most energetic earthquake swarm in Hawaii recorded history. The swarm altered 4 to 5 sq mi (10 to 13 km 2) of the seamount's summit; one section, Pele's Vents, collapsed entirely upon itself and formed the renamed Pele's Pit.

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.
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 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]
