The Andromeda galaxy is on a collision course with the Milky Way
The Andromeda galaxy is speeding towards the Milky Way, destined for a dramatic merger in roughly 4.5 billion years that will transform our night sky.
Our galactic neighbor, the Andromeda galaxy, is hurtling towards the Milky Way at 110 kilometers per second. This cosmic encounter, confirmed by astronomers observing its blueshift, will dramatically reshape our local universe. While stars are unlikely to collide directly, gravitational forces will merge the two spiral galaxies into a new, larger elliptical galaxy, sometimes called Milkomeda. This spectacular event is expected to unfold in about 4.5 billion years, long after our Sun has expanded.
