Almost certainly, but our observational span may be too short to really know.

This Galaxy is about 70% larger than out Milky Way galaxy. The rotation of astronomical bodies is most probably the net sum of the movements of the individual members.

M101, the Pinwheel Galaxy, appears to have several arms, and perhaps its central globular cluster is a smaller proportion of its galaxy than usual. But what is usual?
