Messier 31

Vern's picture

M31 or NGC 224, the Andromeda Galaxy in the constellation Andromeda is located approximately 2.5 million light years from our solar system. If you are fortunate to be at a location far from city lights next week, you may be able to see it without optical aid. It is a spectacular sight in binoculars. If sky is transparent and very dark it will nearly fill half the view. Studies by the Spitzer space telescope in 2006 suggest that it may contain a trillion stars.
