It is a normal appearing elliptical galaxy. Recently it has been shown that collisions play an important role in the life cycles of galaxies, so we know that what is going on in this picture is important. A typical place for stars to form is in an area of dense nebular gas, which is common to the arms in spiral galaxies. Sometimes a burst of star formation can occur with unusual geometry. For example, the nearby galaxy NGC 1317 shows an unusual ring of star formation surrounding its barred nucleus.
Older stars appear more red and are more evident in the leftmost photograph in visible light.
The rightmost photograph was taken by the Ultraviolet Imaging Telescope. It highlights the stars which are younger and bluer and it shows the starburst ring. This unusual ring may be evidence of a gravitation encounter with another galaxy, which may be causing a density wave to ripple out from the galaxy's center. NGC 253 is a spiral galaxy that is almost sideways in this picture. It is the largest member of the Sculptor Group of Galaxies, which is the closest group to our own local group.
