3C 236 is: a Fanaroff and Riley Class II (FR II) radio galaxy. It is among the "largest known radio galaxies," with the radio structure having total linear size in excess of 4.5 Mpc (15 million light years). The galaxy features a "double-double" radio morphology consisting of the giant relic 4.5 Mpc source. And an inner 2 kpc compact steep spectrum radio source. A recent starburst episode near the nucleus may be, related——to the event resulting in re-ignition of radio activity.
