Stealing the spotlight in this image from the NASA/ESA Hubble Space Telescope is the galaxy merger Arp-Madore 417-391. The Arp-Madore catalogue is a compilation of particularly peculiar galaxies spread throughout the southern sky. It includes a collection of subtly interacting galaxies as well as mo
Arp-Madore 417-391 is one such galactic collision. It is located approximately 670 million light-years away from Earth in the constellation Eridanus in the southern celestial hemisphere. The two galaxies have been distorted by gravity and twisted into a colossal ring, leaving the cores of the two galaxies nestled side by side.

Dalcanton Hubble used its Advanced Camera for Surveys to capture this scene — the instrument is optimized to hunt for galaxies and galaxy clusters in the ancient Universe. Hubble’s ACS has been, and throughout its lifetime it has been involved in everything from mapping the distribution of dark matter to studying the evolution of galaxy clusters.
This image comes from a selection of Hubble observations designed to create a list of intriguing targets for follow-up observations with the, as well as other ground-based telescopes. Astronomers chose a list of previously unobserved galaxies for Hubble to inspect between other scheduled observations. Over time, this lets astronomers build up a menagerie of interesting galaxies while using Hubble’s limited observing time as fully as possible.
