Messier 101 also known as the Pinwheel galaxy in the constellation Ursa Major is a classic face on spiral galaxy. This giant spiral galaxy is approximately 170,000 light-years across, nearly twice the diameter of our galaxy, the Milky Way. M101 is estimated to contain at least one trillion stars. The galaxy’s spiral arms are sprinkled with large regions of star-forming nebulae. These nebulae are areas of intense star formation within giant molecular hydrogen clouds. Hope you all enjoy and thanks for any constructive comments.
