    In the center is an elliptical galaxy (smooth, "in between"); on its left-hand edge is a blue blob. Because it's a blob, and not star-like, it's very likely also a galaxy. The blue color suggests that star-formation is on-going, and that it's reasonably close (i.e. redshift less than ~0.1). Whether it's interacting with the elliptical is not clear (to me anyway; I can't see any signs of any interaction). If so, then it's an overlap, with the blue blob likely in the foreground (there's a faint hint of a dimming of the elliptical on the left vs the right).

    But that's just my interpretation; other zooites may have different interpretations (isn't GZ wonderful?)

    Happy hunting! 😃
