Here's an interesting trio of galaxies in the constellation Coma Berenices. The large spiral is called NGC 4725 and the gravitational interaction between it and NGC 4747 (above right) has caused those tidal tails to be pulled out. The smaller galaxy below is NGC 4712. There are other galaxies in the shot too.
