About this Image

This radio galaxy is associate with the central dominant elliptical galaxy of a nearby cluster. The overall linear size of the radio structure is 120 kpc. It is a complex double-lobed radio source, with highly filamentary lobes, and a narrow jet and counterjet. The jet feeds the bright hot spot, and the less stable counterjet thrashes over the lobe. The radio emission is from relativistic streams of high energy particles generated by the radio source in the center of the radio galaxy. Astronomers believe that the jets are fueled by material accreting onto a super-massive black hole. The high energy particles are shot into extragalactic space at speeds approaching the speed of light, where they eventually balloon into massive radio lobes.
