Description

This object is two interacting galaxies located 40 million light years away in the constellation of Leo Minor. NGC 3432 is the main spiral galaxy seen in the image. UGC 5983 is the dim dwarf galaxy seen slightly above and to the right of the spiral galaxy. Many bright blue star clusters are seen throughout the spiral galaxy, although the clusters do not line up precisely with the disk.

The gravitational interaction between these two galaxies is evident by the undulating structure of the spiral galaxy disk, easily seen from our edge-on view. The knot to the left of the galaxy is also unusual in its distance from the main disk.

Usually this type of interaction leads to starburst activity, but I did not detect a strong Ha signal in the spiral galaxy, nor did I see any pinkish hues. Scientists believe that there is usually a lag between galaxy interaction and starburst activity. This galaxy may still be in the lag phase, indicating that the interaction is fairly recent relative to space time.
