PKS 0637-752 is a quasar located six billion light years in the constellation of Mensa.[1] It is noted for having a bright and largest astrophysical jet at redshift of z = 0.651.[2][3] Discovered by Einstein Observatory in 1980 through X-rays,[4] PKS 0637-752 was the first celestial object to be observed by Chandra X-ray Observatory upon its commissioning in July 23, 1999.[5]
