Astronomers have long thought the Milky Way was destined to merge with the nearby Andromeda galaxy. The aftermath of this predicted clash has been dubbed “Milkomeda,” and researchers predicted it would happen in four or five billion years.

Astronomers reported Monday that the probability of the two spiral galaxies colliding is less than previously thought, with a 50-50 chance within the next 10 billion years. That’s essentially a coin flip, but still better odds than previous estimates and farther out in time.

New research shows that there's a 50% chance that the Milky Way and its nearest major galactic neighbor, the Andromeda Galaxy, will converge within the next 10 billion years. Previous analyses have made out the convergence to be a sure-fire thing,
