A quasar (/ˈkweɪzɑːr/ KWAY-zar) is an extremely luminous active galactic nucleus (AGN). It is sometimes known as a quasi-stellar object, abbreviated QSO...

gravitational lensing appear as multiple images on Earth. This is a list of double quasars, triple quasars, and the like, where quasars are close together in line-of-sight...

The Cloverleaf quasar (H1413+117, QSO J1415+1129) is a bright, gravitationally lensed quasar. It receives its name because of gravitational lensing spitting...

The Quasar is a semi-enclosed feet forward motorcycle, created by Malcolm Newell and Ken Leaman, who made a number of similar vehicles. It repurposed an...

UHZ1 is a background galaxy containing a quasar. At a redshift of approximately 10.1, UHZ1 is at a distance of 13.2 billion light-years, seen when our...

oldest known quasar at z = 7.64, at the time of its discovery. In January 2021, it was identified as the most redshifted (highest z) known quasar, with the...

very distant, broad absorption line quasar located in the constellation Lynx. It is magnified and split into multiple images by the gravitational lensing...

When the background source is a quasar or unresolved jet, the strong lensed images are usually point-like multiple images; When the background source...

cosmologically distant objects (in particular galaxies and quasars) tend to cluster around multiples of some particular value. In standard inflationary cosmological...
