2MASX J09133888-1019196 comprises two interacting galaxies that are both disturbed by gravitational interaction. The wide separation of the pair - approximately 130,000 light-years - suggests that the galaxies are just beginning to merge. Together the two galaxies form an ultra-luminous infrared system, which is unusual for the early stages of an interaction. One possible explanation is that the one or both of the components have already experienced a merger or interaction. Giant black holes lurk at the cores of both galaxies, which are found in the constellation of Hydra, the Sea Serpent, about 700 million light-years away from Earth.
This image is part of a large collection of 59 images of merging galaxies taken by the Hubble Space Telescope and released on the occasion of its 18th anniversary on 24th April 2008.
