Description

This object is a spiral galaxy located 50 million light years away in the constellation of Cancer. The galaxy's apparent size to us is less than 5 minutes in diameter. It contains about 100 billion stars and is about one-half the diameter of our Milky Way.

The structure of this galaxy is fantastic - similar to that of one of my favorite galaxies, M94, although smaller and harder for us to see. Moving out from the bright white spherical core, I count as least 6 different types of circular regions including dark dust lanes, star forming areas, and a wispy wide outer ring. I also see many star clusters. The typical spiral arm structure is not present.

NGC 2775 is the largest galaxy in a small group known as, strangely enough, the NGC 2775 group. A number of these galaxies are visible in the image, including NGC 2777 towards the upper right and NGC 2773 towards the lower right.
