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).

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.
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.
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 ...
This is a radio galaxy. This was the remotest object known at time of discovery of its redshift. This was the last non-quasar to hold the title of most distant object known until 1997. In 1964, quasar 3C 147 became the most distant object in the universe known. [76] [83] [97] [98] [99] LEDA 25177 (MCG+01-23-008) 1951–1960: z=0.2 (V=61000 km/s)
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 ...
Since these objects could be observed visually with the relatively small-aperture refracting telescope (approximately 100 mm ≈ 4 inches) used by Messier to study the sky from downtown Paris, they are among the brightest and thus most attractive astronomical objects (popularly called deep-sky objects) observable from Earth, and are popular ...
