GRB 221009A was an extraordinarily bright and very energetic gamma-ray burst (GRB) jointly discovered by the Neil Gehrels Swift Observatory and the Fermi Gamma-ray Space Telescope on October 9, 2022. The gamma-ray burst was ten minutes long, [ 1 ] but was detectable for more than ten hours following initial detection.
Objects may have been discovered without distance determination, and were found subsequently to be the most distant known at that time. However, object must have been named or described. An object like OJ 287 is ignored even though it was detected as early as 1891 using photographic plates, but ignored until the advent of radiotelescopes.

The brightest gamma ray burst ever detected recently reached Earth. It’s 70 times longer than any other burst we’ve spotted.
Astronomers have discovered what may be the brightest object in the universe, a quasar with a black hole at its heart growing so fast that it swallows the equivalent of a sun a day. The black hole ...
[65] [66] However, in January 2011, 10-year-old Kathryn Aurora Gray from Canada was reported to have discovered a supernova, making her the youngest ever to find a supernova. [67] Gray, her father, and a friend spotted SN 2010lt , a magnitude 17 supernova in galaxy UGC 3378 in the constellation Camelopardalis , about 240 million light years away.
A comet that orbits the Sun every 160,000 years will appear in the night sky this week, offering a rare chance. The Comet C/2024 G3 (ATLAS) is expected to be the brightest comet in nearly 20 years ...
GN-z11 is a high-redshift galaxy found in the constellation Ursa Major.It is among the farthest known galaxies from Earth ever discovered. [5] [6] The 2015 discovery was published in a 2016 paper headed by Pascal Oesch and Gabriel Brammer (Cosmic Dawn Center).
