Glenn's Astrophotography




M81, also known as Bode's Galaxy, is a type Sb spiral galaxy located in the constellation of Ursa Major. It is a beautiful example of what is known as a "grand design" spiral galaxy. It's prominent spiral structure and dense star forming regions is a result of a strong gravitational influence with its neighboring galaxy, M82. M81 is located approximately 12 million light-years from earth.
