One of the big mysteries in astronomy is how galaxies grow and evolve over time. Collisions between galaxies are thought to be key events that shape their development. A stunning collection of 59 new images of colliding galaxies has been released to mark the 18th anniversary of the NASA/ESA Hubble Space Telescope. They give us a unique insight into how galaxies collide to form larger galaxies.
