Messier 81 is a spiral galaxy about 12 million light-years away in the constellation Ursa Major. Messier 81 was first discovered by Johann Elert Bode in 1774. Originally referred to as Bode's Nebula, it wasn't until the 20th century when Hubble determined that these certain "nebulae" were actually outside the Milky Way and galaxies on their own. The M81 group of about 34 galaxies are roughly 12 mly from Earth and it's Local Group of galaxies and our nearest neighbor in the Virgo Supercluster.
A spiral galaxy approximately 3 million light years from Earth in the constellation Triangulum. Also referred to as the Pinwheel galaxy, it is the third largest galaxy in the local group.
