ULAS J1120+0641
Extremely distant quasar
ULAS J1120+0641 is a quasar in the constellation Leo. It was discovered in June 2011.[1] It was the most distant known quasar but then an another quasar named ULAS J1342+0928 was found in 2017 was found further away.[2][3][4] It is at a projected comoving distance of 28.85 billion light years and was the first quasar found beyond a redshift of z = 7.[5]
