The highest-redshift quasar known (as of August 2024) is UHZ1, with a redshift of approximately 10.1, [48] which corresponds to a comoving distance of approximately 31.7 billion light-years from Earth (these distances are much larger than the distance light could travel in the universe's 13.8-billion-year history because the universe is expanding).
These were the most remote objects discovered at the time. The pair of galaxies were found lensed by galaxy cluster CL1358+62 (z = 0.33). This was the first time since 1964 that something other than a quasar held the record for being the most distant object in the universe.

Size comparison of the event horizons of the black holes of TON 618 and Phoenix A.The orbit of Neptune (white oval) is included for comparison. As a quasar, TON 618 is believed to be the active galactic nucleus at the center of a galaxy, the engine of which is a supermassive black hole feeding on intensely hot gas and matter in an accretion disc.
At the time, the most remote object was quasar OQ172, at z=3.53, found in 1974. [76] From 1964 to 1997, the title of most distant object in the universe were held by a succession of quasars. [83] That list is available at list of quasars. 3C 295: 1960– z=0.461 This is a radio galaxy. This was the remotest object known at time of discovery of ...
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 ...
The unusually bright quasar is located 13 billion light-years away and experts say the discovery could unlock clues about our universe’s early beginnings. The brightest celestial object in the ...
The universe’s brightest object is a quasar in a distant galaxy that’s powered by the fastest-growing black hole ever recorded, according to a new study.
