NGC 6240 is a peculiar, butterfly- or lobster-shaped galaxy consisting of two smaller merging galaxies. The galaxies, which lie in the constellation of Ophiuchus, the Serpent Holder, some 400 million light-years away, are expected to complete their merger in tens to hundreds of millions of years. As they do, two giant black holes will drift toward one another and eventually merge together into a larger black hole, scientists say.

I want to see what happens when two black holes merge....
In this image, a feather-like galaxy crosses a companion galaxy. The two components will probably merge to form a single galaxy in the future. Dubbed ESO 593-8, they are located in the constellation Sagittarius, the Archer, some 650 million light-years from Earth.
