“How close they come on their first passage is very uncertain, however, and if they don’t come very close, meaning if their distance is more than around 500,000 light-years, they might not ...

It's a fun fact pulled out at parties by every space nerd on the block — our Milky Way galaxy is going to crash into our nearest neighbour (the Andromeda galaxy) in 5 billion years. But ...

The Milky Way and Andromeda experience at least one close encounter, passing each other by at a distance of 500,00 light years, in a little more than half of the simulations, before they lose so ...
