ANTENNAE GALAXIES45 million light-years The Antennae are two galaxies in the process of merging. The cores of the galaxies are seen in yellow, while blue stars and red star-forming regions show the spiral arms in their complex interweaving dance. Astronomers think this is the fate awaiting us when the Milky Way and our neighbour, the Andromeda Galaxy, collide in a few billion years.
