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″ [5] [6] [7] SDSS J1029+2623 3 Galaxy cluster at z = 0.6 The current largest-separation quasar lens with 22.6″ separation between furthest images [8] [9] [10] SDSS J2222+2745 6 [11]
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. Given its observed redshift of 2.219, the light travel time of TON 618 is estimated to be approximately 10.8 billion years.

Largest-known large quasar group and the first structure found to exceed 3 billion light-years. "Giant Arc" (2021) 3,300,000,000 [12] Located 9.2 billion light ...
Ton 618 (this quasar has possibly the biggest black hole ever found, estimated at 66 billion solar masses) [1] 3C 371; 4C +37.11 (this radio galaxy is believed to have binary supermassive black holes) [2] AP Lib; S5 0014+81 (said to be a compact hyperluminous quasar, estimated at 40 billion solar masses) [3]
At a distance of more than 13.03 billion light years from Earth, J0313–1806 is the most distant— and thus the most ancient — quasar yet seen by astronomers.
