3C 321 is a system of two galaxies rotating around each other. They are notable for showing the first observed galaxy smiting another galaxy with a blast of energy, which is theorized to be from a supermassive black hole at the center of the former galaxy.
The larger galaxy, dubbed the "Death Star Galaxy" by NASA astronomers, has an energetic jet directed towards its companion. The discovery was announced by NASA on 18 December 2007. Observation of the enormous jet was possible due to the combined efforts of both space and ground-based telescopes.
