The first star in the list, Godzilla [1] — an LBV in the distant Sunburst galaxy — is probably the brightest star ever observed, although it is believed to be undergoing a temporary episode of increased luminosity that has lasted at least seven years, in a similar manner to the Great Eruption of Eta Carinae that was witnessed in the 19th ...

[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.
More than 900,000 quasars have been found (as of July 2023), [6] most from the Sloan Digital Sky Survey. All observed quasar spectra have redshifts between 0.056 and 10.1 (as of 2024), which means they range between 600 million and 30 billion light-years away from Earth. Because of the great distances to the farthest quasars and the finite ...
The brightest gamma ray burst ever detected recently reached Earth. It’s 70 times longer than any other burst we’ve spotted.
3C 273 is a quasar located at the center of a giant elliptical galaxy in the constellation of Virgo.It was the first quasar ever to be identified and is the visually brightest quasar in the sky as seen from Earth, with an apparent visual magnitude of 12.9. [2]
