About this Image
The Centaurus A galaxy is situated in the M83 group of galaxies. It is one of the most interesting and peculiar galaxies in the sky,
and is a strong source of radio radiation (therefore the designation Centaurus A); it is actually the nearest radio galaxy. It is of intermediate type between elliptical and disk (spiral) galaxies: The main body has all characteristics of a large elliptical, but a pronounced dust belt is superimposed well over the center, forming a disk plane around this galaxy.
The distance to the galaxy is approximately 15 million light years.
