This artwork depicts a pair of fictitious spiral galaxies in the midst of a merger. Galaxies are relatively closely separated in extragalactic space compared to their size, so interactions and mergers between them are quite common. The Milky Way, for example, will one day merge with its neighbouring galaxy, Andromeda. It is thought that galaxy mergers are one of the ways in which galaxies evolve into new forms.
