NGC 3608 is an elliptical galaxy located in the constellation Leo.

There is diffuse X-ray emission coming from this galaxy and NGC 3607, which suggests that the two may be merging.

The blue globular clusters have a more extended distribution throughout the galaxy.

Overall, the globular clusters are aligned along an axis that is not the same as the rest of the stars, which may be further evidence of galaxy interaction with NGC 3607.
