A burst as energetic and as close to Earth as 221009A is thought to be a once-in-10,000-year event. [10] [9] It was the brightest and most energetic gamma-ray burst ever recorded, with some dubbing it the BOAT, or Brightest Of All Time. [9] [11] [12] [13]
The brightest gamma ray burst ever detected recently reached Earth. It’s 70 times longer than any other burst we’ve spotted. Scientists Have Found the 'BOAT' Gamma Ray Burst—the Brightest of ...
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]
Artist's rendering of the accretion disc in ULAS J1120+0641, a very distant quasar containing a supermassive black hole with a mass two billion times that of the Sun [1] The Chandra X-ray image is of the quasar PKS 1127-145, a highly luminous source of X-rays and visible light about 10 billion light-years from Earth.
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 ...

Brightest known high-redshift source of CO emission [4] QSO B1359+154: 6 CLASS B1359+154 and three more galaxies First sextuply-imaged galaxy SDSS J1004+4112 5 Galaxy cluster at z = 0.68 First quasar discovered to be multiply image-lensed by a galaxy cluster and currently the third largest quasar lens with the separation between images of 15 ...
The object itself was detected in ESO images dating back to 1980, but its identification as a quasar occurred only several decades later. [2]An automated analysis of 2022 data from the European Space Agency's Gaia satellite did not confirm J0529-4351 as too bright to be a quasar, and suggested it was a 16th magnitude star with a 99.98% probability.
