Quasar Images Lens Notes Twin Quasar: 2 YGKOW G1: First gravitationally lensed object discovered : Triple Quasar (PG 1115+080) 4 Originally discovered as 3 lensed images, the fourth image is faint. It was the second gravitationally lensed quasar discovered. Einstein Cross: 4 Huchra's Lens: First Einstein Cross discovered RX J1131-1231's quasar 4
A multiple-image quasar is a quasar whose light undergoes gravitational lensing, resulting in double, triple or quadruple images of the same quasar. The first such gravitational lens to be discovered was the double-imaged quasar Q0957+561 (or Twin Quasar) in 1979. [ 75 ]

The ULAS J1342+0928 quasar is located in the Boötes constellation. [3] The related supermassive black hole is reported to be "780 million times the mass of the Sun". [5] At its discovery, it was the most distant known quasar. In 2021 it was eclipsed by QSO J0313-1806 as the most distant quasar. [8]
Quasars, though, are on the small end of the supermassive black hole size class—sometimes just a few days across, or about 1,000 of the distance between Earth and the Sun, Space.com explains ...
This is a list of the largest cosmic structures so far discovered. The unit of measurement used is the light-year (distance traveled by light in one Julian year; approximately 9.46 trillion kilometres). This list includes superclusters, galaxy filaments and large quasar groups (LQGs). The structures are listed based on their longest dimension.

ULAS J1120+0641 was discovered by the UKIRT Infrared Deep Sky Survey (UKIDSS), using the UK Infrared Telescope, located in Hawaii. [10] The name of the object is derived from UKIDSS Large Area Survey (ULAS), the name of the survey that discovered the quasar, and the location of the quasar in the sky in terms of right ascension (11h 20m) and declination (+06° 41').
