ULAS J1120+0641

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]
