PSO J172.3556+18.7734

PSO J172.3556+18.7734 is an astrophysical jet that was discovered in May 2011. It was originally thought to be a quasar by astronomers, but as of March 8, 2021, it is now classified as a cosmic jet (astrophysical jet).^[1]^[2] As of 2021^[update], it is the farthest radio-loud quasar discovered with a redshift of 6.82.^[3]^[4]^[5]
