We’re on a collision course with the Andromeda Galaxy — here’s what will happen to Earth

An epic war is coming between our home galaxy and the Andromeda Galaxy, which is currently racing toward us at a speed of 250,000 mph.

Astronomers estimate 3.75 billion years from now, Earth will be caught up amidst the largest galactic event in our planet’s history, when these two giant galaxies collide.

Luckily, experts think that Earth will survive, but it won’t be entirely unaffected — the collision will unfold right in front of us, changing the night sky to look like nothing any human has seen before.

Join us on a journey into the future to see what it will be like:

Right now, Andromeda is about 2.5 million light years away. But when it collides with our galaxy in less than 4 billion years, it will enter into a cataclysmic dance lasting billions of years that will rip both it and the Milky Way apart to form a brand new galaxy.

Just before Andromeda collides, Earthlings will have a gorgeous view. On the left you can see Andromeda as it approaches the Milky Way through mutual gravitational attraction:
