In honor of Hubble's 18th anniversary (24 April, 2008), 59 images were released showing various colliding galaxies.

This image is of Arp 148 ("Mayall's object") located in the constellation Ursa Major, about 500 million light-years away and shows a ring-shaped galaxy and an accompanying long-tailed galaxy after they collided
