Milky Way and Andromeda Galaxy: Potential Collision Ahead

The Milky Way and Andromeda Galaxy are edging closer at 120 km/s, with a predicted collision in 5 billion years. Recent findings suggest a 50% likelihood of collision, potentially occurring in 8 billion years.

External galaxies like Triangulum and Large Magellanic Cloud could alter their trajectory. The merging would create an elliptical galaxy with fused black holes.

NASA forecasts the collision to start in 3-4 billion years, lasting an additional 3 billion. Data from Gaia and Hubble telescopes offer insights into this cosmic spectacle.
