Description

This object, also known as IC 356, is a rarely imaged spiral galaxy located 40 million light years away in the constellation of Camelopardalis at a declination of +70 degrees. The galaxy spans 6 arc-minutes in our apparent view, which corresponds to a diameter of 70,000 light years. Because this galaxy is heavily obscured by dust, the disk appears a bit blurry and orange in color.

This is one of the most interesting galaxy structures I have ever seen. As seen in the full resolution view, there appear to be 2 bright cores, side by side. Even more interesting, around these 2 cores is a dark dust band which circles the cores and which extends radially from the cores to the upper right galaxy edge. It appears that there may have been a galaxy merger which retained a spiral structure but with none of the typical merger characteristics of disk distortion or star streams. 

It is possible, I guess, that the dark band is a foreground Milky way structure, especially since the rest of the disk appears a bit mottled. But I prefer to think of this as a galaxy with a fascinating structure.

Several other distant spiral galaxies are visible in the background.
