The largest, the furthest, the most powerful, and to some of us the most fascinating objects known in the Universe are to be found among the radio sources associated with some elliptical galaxies and QSO’s. In recent years it has become apparent that they are also objects of considerable beauty.. Here’s the Story We’ll Unfold for You….
