The compact core is the relatively bright spot on the north edge of the southern lobe.

The bright and compact hotspots in this famous object have been studied by Rudnick (1988) and Rudnick & Anderson (1990). The bright southern hotspot has also been detected in the optical Meisenheimer et al. 1997). Our image puts the hotspots into context by showing the extensive but faint bridge between the hotspots.

The host galaxy is not a typical elliptical. There is a rather strong bar visible in the HST image (Zirbel & Baum 1998), and there is knotty structure in the UV which suggests star formation (Hurt et al. 1999). However, this could also be due to the large reflection nebula detected in optical polarization, which reveals that this classical narrow-line radio galaxy has a hidden broad-line nucleus (Cohen et al. 1999).
