M101 - Galaxy in Ursa Major
The Messier Ten Minute Challenge
M101 - Galaxy in Ursa Major The spiral galaxy M101 is a beautiful, large, face-on spiral galaxy. Several knots of emission nebulosity and star forming regions with NGC designations can be seen in this image. M101 is of a notable non- symetrical shape with its core being considerably displaced. Cepheid variables suggest a distance of about 22 million light-years. http://www.martin-nicholson.info/ten...lenge/m101.htm Martin Nicholson, Daventry, England. http://www.martin-nicholson.info/1/1a.htm Visit the Astronomical Hall of Shame at http://www.geocities.com/queen5658/
