PGC 10922 is an example of a lenticular galaxy—a type that lies on the border between ellipticals and spirals. Seen face-on, this Hubble image shows the disk and tightly-wound spiral structures of dark dust encircling the bright center of the galaxy. There is also an outer halo of faint wide arcs or shells extending outward. These may have have been formed by a gravitational encounter or perhaps a merger with another galaxy.
