This object is a spiral galaxy located 220 million light years away in the constellation of Hercules. Its apparent diameter of 3 arc-minutes is small. But because it is so far away, the actual diameter is almost 200,000 light years, twice the diameter of our Milky Way.

The galaxy has a number of interesting features. The outer regions of the galaxy have a pinkish tint, suggesting that it is undergoing a lot of star formation within. The bottom left edge of the galaxy disk has been disturbed and looks to be warped a bit out of plane. Most interesting is that the right half of the inner galaxy arm appears to be filled with numerous bright blue star clusters and is much bluer than the left side.

All of these signs point to a gravitational interaction with another galaxy, but where is the culprit? Scientists believe that the comet-like smudge to the lower right of NGC 6632 is the companion galaxy for this interaction. Not much is left of the companion, which is designated galaxy 2MASXJ18245534+2730302.

I cropped this image significantly because of a bright distracting star that is just off image.
