Radio galaxies are usually elliptical. They often exhibit jet structure from a compact nucleus. They typically exhibit two lobes of radio frequency emission that are often approximately aligned with the jets observed in the visible spectrum and that may extend for millions of light years.
The giant elliptical galaxy M87 in the Virgo cluster is another example of a nearby radio galaxy. Here is a montage showing M87 surrounded by its globular clusters and showing a jet emanating from its nucleus. The optical jet of M87 is quite spectacular in this image, which is a composite constructed to enhance the jet relative to the rest of the galaxy (see this discussion).
Another spectacular example of a jet from an active galaxy is the "blowtorch" of the galaxy NGC6251 (see this discussion). Finally, here are images of jets from 4 radio galaxies with an explanation.
Generally, the optical counterparts for these radio lobes are very small compared with the extent of the radio lobes. For Fornax A the optical counterpart is about the size of the gap between the two lobes; for the other sources the optical counerparts are even smaller.
