Caption: Astronomers think that our Milky Way galaxy will collide with our neighbor spiral galaxy, Andromeda, several billions of years from now. This artist’s illustration depicts just such a collision in its early stages, which is one of the ways that galaxies grow. Studying galaxy collisions can help scientists learn about the Universe when it was much younger and these kinds of galactic mergers were much more common.
