Radio Glaxy 4C 73.08

I don't want to publish an astronomy picture just because it's pretty, but I'll make an exception for this.  In any case, 4C 73.08 is a very interesting object.





This Hubble picture of a small cluster of galaxies shows several spiral galaxies; some viewed face on, some viewed edge-on.

The most striking object, however, is the large elliptical galaxy in the upper centre of the image. The supermassive black hole at it's core is ejecting twin jets of material.  These jets of material are not visible optically, however, they emit huge amounts of radio energy.  Hence 4C 73.08's designation as a radio galaxy.
