The Pinwheel Galaxy

M 101, RGB

April 27th, 2017

I got very little data on this one (and it’s quite faint), so not my best attempt.

M 101 (otherwise known as the pinwheel galaxy) is a large face on spiral galaxy in Ursa Major. At around 21 million light years this galaxy is fairly close, allowing for the inspection of the star forming arms. This galaxy has been distorted by one or more nearby companions, throwing the outer arm out of it’s typical orbit.
