They are in the NGC 4038 group with five other galaxies. These two galaxies are known as the Antennae galaxies because they have two long tails of stars, gas and dust ejected from the galaxies as a result of the collision. The nuclei of the two galaxies are joining to become one giant galaxy.
These interacting galaxies are nearer the Milky Way than previously thought—at 45 million light-years instead of 65 million light-years.
