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.

The team found only a 2 percent probability that the galaxies will collide in the next five billion years. In slightly over half of the simulated scenarios, Andromeda and the Milky Way experience at least one close encounter before they lose enough orbital energy to collide and merge.
