4 billion years from now

4 billion years from now, our galaxy, the Milky Way, will collide with our large spiraled neighbor, Andromeda. Currently, Andromeda and the Milky Way are about 2.5 million light-years apart. Fueled by gravity, the two galaxies are hurtling toward one another at 402,000 kilometers per hour. But even at that speed, they won’t meet for another four billion years. Then, the two galaxies will collide head-on and fly through one another, leaving gassy, starry tendrils in their wakes. For eons, the pair will continue to come together and fly apart, scrambling stars and redrawing constellations until eventually, after a billion or so years have passed, the two galaxies merge. 🔭 Image credits: SaltyKanan Check out the link in our bio for some really awesome space decor! 👩‍🚀
