Astronomers thought the Milky Way was doomed to crash into Andromeda. Now they're not so sure For years, astronomers have predicted a dramatic fate for our galaxy: a head-on collision with Andromeda, our nearest large galactic neighbor. This merger—expected in about 5 billion years—has become a staple of astronomy documentaries, textbooks and popular science writing.

Stunning image of Arp 87, a pair of interacting galaxies locked in a gravitational dance. A bridge of stars, gas, and dust, spanning over 75,000 light-years, connects the two galaxies, showcasing the violent effects of their close encounter. The right galaxy, NGC 3808A, displays vibrant blue star clusters, evidence of recent star formation triggered by the interaction. The left galaxy, NGC 3808B, is an edge-on spiral wrapped in bridging material, with a unique polar ring. This image depicts a common, yet visually striking, stage in the eventual merger of these two galactic systems, located approximately 300 million light-years away in the constellation Leo. A more distant background galaxy is visible at the far left.
