Andromeda-Milky Way Galaxy Smash-Up May Not Happen As Soon As Expected Learn about the new research that changes the estimates of the Milky Way’s demise.

The initial measurements from Hubble a decade ago seemed to solidify the head-on collision scenario, as Andromeda's sideways motion appeared negligible.

For this new study, the scientists relied on updated galaxy measurements to factor in the gravitational pull on the Milky Way's movement through the universe.
