Description

This Astrobin Debut Object is a lenticular galaxy located 80 million light years away in the constellation of Leo Minor at a declination of +28 degrees. This magnitude 12 galaxy spans 2.5 arc-minutes in our apparent view, which corresponds to a diameter of 60,000 light years.

In his Arp catalog, Dr. Arp classified this object into the category of Galaxies with Diffuse Filaments.

The interesting aspect of this galaxy is its structure - it has both a spherical halo and a disk. Studies have identified different gas disk rotational motions in the galaxy, suggesting that the structure could be the result of a merger. Perhaps the merger was between an elliptical and a spiral, leading to the current structure.

Arp's image has some structure that is not present in my image. Some of this structure does not look quite "natural" to me and I am not sure what to think of it.

Several smaller galaxies are visible in the background but none appear to be at the same distance as the subject galaxy.
