M74 - Galaxy in Pisces
The Messier Ten Minute Challenge
M74 - Galaxy in Pisces Messier 74 (NGC 628) is a prime example of a spiral galaxy but with its low surface brightness it is one of the more difficult objects in Messier objects. Situated at a distance of about 35 million light years it has a diameter of about 95,000 light years - roughly the same as the Milky Way. There are an amazing 193 known HII regions in the spiral arms. http://www.martin-nicholson.info/ten...llenge/m74.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/
