Astronomers say that a collision between the Milky Way and Andromeda may not be a forgone conclusion and “we could avoid this fate entirely.” NASA, ESA, Z. Levay and R. van der Marel (STScI ...

Until now, it has been assumed that the Milky Way and the Andromeda galaxy are on a collision course. However, they may miss each other for the time being.
