3C 348; z=0.154

This source, also known as Hercules A, is a cluster cD galaxy. 3C 348 is a double-galaxy system in the process of merging [Sadun and Hayes1993]. The radio core coincides with the southeastern galaxy. This galaxy has faint dust rings around the core in this near-infrared image. These rings are discussed in detail by [Baum et al.1996] based on WFPC2 observations.
