The Milky Way is on a crash course with the Andromeda galaxy, but what would a galactic collision actually look like? What Happens When Galaxies Die? - https://youtu.be/wWvJVE5nio4 Read...
========== It might be odd to get your head around, but
galaxies can and do collide. But far from an wild party of death, galaxies
collisions yield hotbeds for new star formation, leading astronomers to suspect that this not-so-violent
event is actually a driving factor behind galactic evolution. The big question here is how can galaxies
collide and not just destroy everything? It helps to think about what a galaxy really
is. Every galaxy is made up of some 100 billion
stars with planets orbiting their host stars, but those stars are really far apart. Take the Milky Way for example. We’re about here on the edge of a spiral
