Galactic Pinwheel

Like a pinwheel, this galaxy spins seemingly with the help of unseen cosmic breath. The Pinwheel Galaxy also known as Messier 101 or NGC 5457, is a face-on spiral galaxy at a distance of 21 million light-years away in the constellation Ursa Major. With a diameter of about 170,000 light years it is 70 percent larger than our own Milky Way Galaxy.
