"Fifty-nine new images of interacting galaxies make up the largest collection of images provided by Hubble. These galaxies are found throughout the Universe, sometimes dramatic events occur as collisions that cause bursts of star formation, on other occasions with stealthy mergers give rise to new galaxies.
Merging Galaxies were more common in the early universe at present, it is believed that these are one of the main driving forces for cosmic evolution. Even apparently isolated galaxies show signs in their internal structure having suffered one or more mergers in their past.
Our own Milky Way contains the rubble of many smaller galaxies it has encountered and devoured in the past, and is currently absorbing the Sagittarius galaxy. In turn, it seems as if our Milky Way joins giant neighbor, the Andromeda galaxy.
Part of galaxies included by Hubble are part of The Atlas of Galaxies, a remarkable catalog produced by the astronomer Halton Arp in the mid 1960's that built on work by BA Vorontsov-Velyaminov 1959. Today, the peculiar structures seen by Arp and others are understood as the result of complex gravitational interactions. "
