Finnish Researchers: There Is a 50% Chance that Our Galaxy Will Collide with Andromeda in the Future
"Currently, reports of the impending end of our Galaxy seem to be greatly exaggerated." This is the conclusion scientists have drawn from a...
Although a collision was considered almost certain to occur within the next 5 billion years, new simulations extending 10 billion years into the future have determined that the probability of it happening is negligible.

In 1912, astronomers realized that the Andromeda Galaxy, located about 2.5 million light-years away, was heading towards the Milky Way. They corro…
Astronomers Thought The Milky Way Was Doomed To Crash Into Andromeda. Now They’re Not So Sure - Stuff South Africa
For years, astronomers have predicted a dramatic fate for our galaxy: a head-on collision with Andromeda, our nearest large galactic neighbour. This merger – expected in about 5 billion years – has become a staple of astronomy documentaries, textbooks and popular science writing. But in our new study published in Nature Astronomy, led by Till Sawala from the University of Helsinki, we find the Milky Way’s future might not be as certain as previo…
New data predicts a 50% chance that the Milky Way and Andromeda galaxies will collide
Scientists have long thought the Milky Way galaxy would someday collide with its closest neighbor, Andromeda. However, new research suggests the future of our cosmic home is more uncertain than previously believed. A detailed study using data from NASA’s Hubble and the European Space Agency’s Gaia telescopes has revealed that the chances of a collision are about even—far from the inevitable scenario scientists once predicted. Mapping the Cosmic …
For decades, astronomers have announced a spectacular destiny for our galaxy: a titanic collision with its closest neighbour, Andromède. An inevitable galactic fusion, expected in about 5 billion years, which would forever transform the structure of the night sky. But a study published on June 2, 2025 in Nature Astronomy comes [...]
The collision between the Milky Way and Andromède, long considered inevitable, may ultimately not occur. Recent simulations question this prediction, which is that...
