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.
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 ).

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. Astronomers just detected the ...

Each black circle and red cross on the upper image map is a quasar similar to this one. The Huge Large Quasar Group , ( Huge-LQG , also called U1.27 ) is a possible structure or pseudo-structure of 73 quasars , referred to as a large quasar group , that measures about 4 billion light-years across.
A giant anaconda species captured recently in the Amazon of Ecuador by a team of scientists is the largest to ever be documented, USA TODAY previously reported, and now, there are images showing ...
