The Milky Way Is Dying — And Andromeda Is Coming

The Milky Way is still forming stars, but its best days are already behind it.

Our galaxy once produced stars far faster than it does today. Now its supply of cold gas is slowly declining, star formation is fading, and in about 4.5 billion years the Milky Way will collide with Andromeda. The result will not be a simple crash of stars, but a vast galactic merger that transforms two spiral galaxies into one aging elliptical galaxy: Milkomeda.

In this episode of Deep Space Unsolved, we explore how galaxies die, why the Milky Way is running out of fuel, what will happen when Andromeda arrives, how the night sky will change, and what remains after the last stars fade into darkness.

The death of a galaxy is not an explosion. It is a slow fading.
