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.. Galaxies are . not. . alike. For every general rule I give, one can find exceptions. Classifying galaxies is difficult. They look different in different wavelengths. If the galaxy is moving, you have to correct for red-shift. Here’s the Story We’ll Unfold for You…. Hubble’s galaxy classifications: Spirals, . ellipticals. , irregulars. . Structural parts of galaxies: disk, halo, nucleus, bulge. Spiral arms – tracers of star formation.
