Pictor A

Double-lobed radio galaxy in the constellation of Pictor

Pictor A, around 485 million light-years away in the constellation Pictor, is a double-lobed broad-line radio galaxy[5] and a powerful source of radio waves in the Southern Celestial Hemisphere.[6] From a supermassive black hole at its centre, a relativistic jet shoots out to an X-ray hot spot 300,000 light-years away.[7]
