This image shows two interacting galaxies lying 40-50 million light-years away in Canes Ventatici. They are speeding away from each other, separated by 24,000 light-years. Both galaxies are thought to have originally been spirals, now distorted by the tidal forces of the interaction. The larger galaxy, NGC 4490, also known as the Cocoon Galaxy and the smaller galaxy is NGC 4485.
