These two galaxies have been slowly merging for eons, and the process is now almost over — indeed, the galaxies now share a single name, NGC 2623. This could be an early preview of our own galaxy’s fate.

The two galaxies that now form the newly born NGC 2623 were likely both once spiral galaxies, roughly the same mass as the Milky Way. Our own galaxy is due to collide and merge with the Andromeda Galaxy in approximately 3.75 billion years. Andromeda is also a spiral galaxy roughly 1.25 times the size of the Milky Way, meaning this collision may well resemble the eventual merger between the Milky Way and its neighbor.
