About this episode

This episode explores the inevitable collision between the Milky Way and Andromeda Galaxy and its implications for our Solar System.

This episode explores the inevitable collision between our own Milky Way and the Andromeda Galaxy (M31) . Currently separated by 2.5 million light-years, these two massive star systems are rushing toward each other at 250,000 miles per hour. We investigate the physics of this cosmic merger and what it means for the future of our Solar System. From the "tidal tails" of gas stripped across the void to the eventual merger of two supermassive black holes at the center, we witness the ultimate evolution of our cosmic home.
