The Pinwheel Galaxy (also known as Messier 101 or NGC 5457) is a spiral galaxy about 27 million light years away in the constellation Ursa Major. M101 is the brightest member of the M101 group of galaxies.
Pinwheel Galaxy was discovered by Messier on Aug. 25, 1764. This very large, almost face-on spiral, contains many star associations, dark nebulas and star forming ( H II ) regions - the most prominent of those, ...

This is M83, the Southern Pinwheel Galaxy. It earned its name from the distinct pinwheel shape of its long spiral arms.
(Added 06/01/04) The Pinwheel Galaxy, more officially named M33, is one of the nearest large galaxies to our own. When scientists study the Pinwheel, they can find clues to how galaxies like ours are born, live, and die.
Astronomers worldwide have been galvanised into action by the discovery of a very young supernova in the Pinwheel galaxy (M101) in Ursa Major.
Here lies our next object, M99, better known as the Pinwheel galaxy. The Pinwheel, otherwise known as NGC 4254, has a brightness between that of M100 and NGC 4450. M99 is a spiral galaxy, much like our own Milky Way in structure.

from the spiral arms through orbital resonance, in effect funneling the flow to create new stars. This process is also thought to explain why many barred spiral galaxies have active galactic nuclei, such as that seen in the Southern Pinwheel Galaxy.
