For decades, astronomers believed that one thing was as certain as death and taxes: the Milky Way and our neighboring Andromeda galaxy were on a crash course… destined to collide in less than 5 billion years.

That galactic smash-up would spark massive star formation, scatter stars like cosmic billiard balls, and possibly throw our Sun into a whole new orbit.

But now… that future may not be so certain.
