The Milky Way has a 50-50 chance of colliding with a nearby galaxy in the next 10 billion years, a new study finds.
But according to a new study, published July 31 on the preprint server arXiv, the two galaxies are just as likely to narrowly miss each other. American astronomer Vesto Slipher discovered Andromeda galaxy's possible collision course with our own in 1912, when he found that Andromeda's light was doppler-shifted to the blue part of the light spectrum due to its approach.
But, according to the researchers behind the new study, these earlier studies did not take into account a"confounding factor" — the gravitational effects of the other, smaller galaxies inside the Local Group to which the Milky Way and Andromeda belong, which could nudge the galaxies away from a crash altogether.

Are Andromeda and the Milky Way doomed to collide? Maybe notScientists discovered the Andromeda galaxy, known as M31, hundreds of years ago, and around a century ago, we realized that it had negative radial velocity toward the Milky Way. In other words, eventually, the two galaxies would merge spectacularly.
