Hubble photographed a strange galaxy with a giant ring

The Hubble mission support team has published a picture of a very unusual-looking galaxy known under the designation Arp-Madore 417-391. It was formed as a result of a “space accident”.

Arp-Madore 417-391 is located at a distance of 670 million light-years from Earth in the direction of the southern constellation Eridanus. It consists of two spiral galaxies in the process of merging. Gravitational interactions have already distorted the original shape of the galaxies and ripped out a significant part of the matter from them, which formed a giant ring structure. It is dotted with a lot of blue lights. These are clusters of newborn stars. At the same time, the Hubble image demonstrates that the galactic nuclei have not yet merged into a single whole.

The photo of Madore 417-391 was obtained using the ACS camera installed on Hubble. The photography was carried out as part of a project to search for unusual objects that could become targets for the James Webb Space Telescope and ground-based observatories. Their observations are conducted during short breaks when engineers deploy Hubble to aim it at another object.

Earlier we talked about how Hubble photographed the intergalactic bridge.
