Galaxy 3C 75

A pair of two galaxies here, in the center of galaxy cluster Abell 400, is melting to become a giant elliptic galaxy. Two supermassive black holes, once the centers of the progenitor galaxies, in a distance of 25 000 light-years now orbit each other. Thereby they emit strong x-ray and radio waves and eject three long jets.
