ANTENNAE GALAXIES45 million light-years The Antennae are two galaxies that are 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 the Milky Way and our neighbour, the Andromeda Galaxy, in a few billion years from now.
