Galaxies can be separated by their appearance into two broad groups, spirals and ellipticals. An example of a spiral galaxy, NGC 1365, is seen in the lower right corner of this picture. In contrast, most of the galaxies in this cluster are ellipticals, which contain little or no gas or evidence of star formation; indeed they are composed millions of rather old, yellowish stars. Unlike many of the stars in spiral systems, those in ellipticals have orbits which are not confined to a narrow plane, so the galaxy can have a shape anywhere between a perfect sphere and an American football. This kind of galaxy is the most common type in the photograph as it is in all of the nearby Universe.

The picture also illustrates another distinctive property of ellipticals, their gregarious nature - they congregate in clusters, like this group of galaxies in > Fornax, 60 million light years distant. We also have a wider field view of the cluster that includes Fornax A (NGC 1316-17) and a much deeper image that shows how large these galaxies are.
