NGC 4676 A and NGC 4676 B, better known as The Mice Galaxies, are a spectacular interacting pair located in the constellation Coma Berenices. They lie at an approximate distance of about 290 million light-years from Earth. This famous system is caught in the midst of a gravitational encounter. As the two spiral galaxies pass close to one another, their mutual gravity distorts their structures and pulls out long tidal tails of stars, gas, and dust. These extended streams are the visible signature of powerful tidal forces, produced as each galaxy stretches and disrupts the other.
