Another Beautiful Galaxy

M101, a mere 25 million light years away, is an Sc, that is, a spiral galaxy, without a central bar and with distinct and somewhat diffuse 'arms'. The blue stars are new and the red ones are old. It's not completely symmetrical (because of interaction with another galaxy, of which 5 are close) and about twice the size of our own galaxy. It is also catalogued as NGC 5457.
It's in the constellation Ursa Major.
