PKS 2126-158 (referred to QSO B2126-158), also known as PKS 2126-15, is a quasar located in Capricornus. It has a redshift of 3.268000, which corresponds to the distance of 11.5 billion light years.[1] It is classified as a gigahertz peaked-spectrum quasar (GPS)[2] with a flat-spectrum radio source[3] and a blazar, a type of active galaxy shooting an astrophysical jet towards Earth.
