3C 153 is a radio galaxy (angular size 6 arcsec=25 kpc) oriented at PA
with an FRII radio morphology and a large arm-length ratio [Laing1981]. It has been classified as a CSS source (e.g. [Akujor et al.1991]) but it would be at the upper end of the size distribution for such sources.
The [OII] emission line nebula is slightly extended along the radio axis [McCarthy et al.1995]. [de Koff et al.1996] note that the galaxy has an elliptical nucleus and strong emission lines.
The NICMOS image shows a fairly round host galaxy. There are a couple of unresolved sources nearby but they don't correlate with knots or hotspots in the radio source. Two other features are caused by the intersection of diffraction spikes.
