Description

This unusual small object is located 130 million light years away in the constellation of Ursa Major. It is entry 155 in the Arp catalog, under the category of "disturbed galaxies with interior absorption". It looks to me to be the result of a recent merger between a spiral galaxy and an elliptical galaxy, but who knows? I couldn't find an image of this object on Astrobin.

The bright spherical core has an apparent diameter of less than one arc-minute. I like the distinct dark dust band which spans the core. Numerous streams are visible, mainly on the right side of the object. The overall size of this object is larger than our Milky Way.

Many small yellowish galaxies are visible in the background near this object.
