The Whale Galaxy and the Crowbar Galaxy. I think the names fit well. Both are near the constellation Canes Venatici. There is a dwarf galaxy on the left edge of the Whale.
These are the Antennae Galaxies. This pair of galaxies, NGC 4038 and NGC 4039, are in a galactic collision. Someday, a few billion years from now, the Milky Way and the Andromeda galaxies will do the same. Here's a LINK showing what that might look like.
