NGC 6240

NGC 6240 galaxy lies 400 million light-years away and has unusual shape as a result of two galaxies merging. In the core, there are two supermassive black holes 3,000 light-years apart, destined to merge into an even bigger black hole.

During the creation of young stars, jets of material, called Herbig-Haro objects, are ejected at high velocities. When they collide with surrounding gas, bow shocks arise as the material heats up.
