Description

This object, also known as NGC 4194, is located 130 million light years away in the constellation of Ursa Major at a declination of +55 degrees. This magnitude 13.3 object spans 3 arc-minutes in our apparent view, which corresponds to a Milky Way like diameter of 120,000 light years.

It was classified by Dr. Arp into the category of Galaxies – Disturbed with Interior Absorption. All of the objects in this Arp category which have interesting star streams and dust lanes.

It looks to me like this is a late stage merger of 2 galaxies. I see signs of both of a spiral galaxy (e.g., flat inner disk and arms) and an elliptical galaxy (star stream shells). The colors of this object indicate star streams (blue), dust bands (brown), and HII regions (pink). I wasn’t confident that these vivid colors were real until I compared my image against the Hubble image.

The star stream ansae-like shell segments (faint at top and clearly seen at bottom), remind me of those of the more famous Arp 189 - Umbrella Galaxy.
