When Galaxies Collide...

Scientists released pictures of merging galaxies today to celebrate the 18th anniversary of the Hubble telescope launch. This collection of images is the largest collection ever released to date.
Colliding galaxies are thought to be a key factor in cosmic evolution although they were more common in the early years of the universe than today. In the most active central period of a galaxy interaction, high levels of infrared and far-infrared radiation are common.
