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.

For astronomers, Omega Centauri has been an outcast amongst globular clusters for a long time. A new result obtained by the NASA/ESA Hubble Space Telescope and the Gemini Observatory provides a surprising explanation for Omega Centauri's peculiarities.

The NASA/ESA Hubble Space Telescope has made the first detection ever of an organic molecule in a planet orbiting another star. This breakthrough is an important step in eventually identifying signs of life on a planet outside our Solar System.

The NASA/ESA Hubble Space Telescope has captured a new image of the galaxy NGC 1132, which is most likely to be a cosmic fossil - the aftermath of an enormous multi-galactic pile-up, where the carnage of collision after collision has built up a brilliant but fuzzy giant elliptical galaxy far outshining typical galaxies.
