The Merger of the Milky Way and Andromeda Galaxies

The Milky Way and Andromeda galaxy are on a collision course! In about 3 billion years, the two galaxies will collide. Then over a span of 1 billion years or so after a very complex gravitational dance, they will merge to form an elliptical galaxy.

When will this collision occur? Plausible orbits and models of the Milky Way and Andromeda galaxies suggest that the big event could occur in as soon as 3 billion years. The Sun will still be burning brightly when this collision occurs and maybe life of some sort will still be around on Earth (or at least within the solar system) at that time.

Unless 'we' can discover inter-galatic travel by then......the human race would be extinct in the 'new' galaxy.

The site has some good pictures of galaxies that are in the midst of colliding and a simulation of the Milky Way and Andromeda galaxies colliding.

Well, considering this wont happen for a few billion years, I don't think
we have anything to worry about.

Plus, who knows, maybe our solar sytem won't be negatively effected.

And by that time, we may be so advanced, that if we wanted, we could
control the galaxies themselves.
