Resolutions Available: 800x600 : 1600x1200
         Object M81 - Bode's Galaxy
         Comment First discovered by Johann Elert Bode in 1774, the grand spiral galaxy M81 (aka NGC3031 or Bode's Galaxy) is one of the nearest galaxies outside our local group. It is the largest galaxy in a group of 34 galaxies located in the constellation Ursa Major. M81's gravitational interaction with nearby galaxy M82 has increased its blue starburst and pink HII regions, stripping matter from M82. M81 resides approximately 12 million light years away.
