ScienceShot: A Mysterious Galactic Halo - ScienceNOW

Galaxies like Milky way or Andromeda are known to be surrounded by halos, primarily consisting of stars from many smaller galaxies. However, something quite different about the "halo" of M81 galaxy is keeping scientists busy. Unusual aspect of this halo is that it appears to be a cloud consisting of much heavier elements than Hydrogen (H) and Helium (He).

The image is taken by Subaru Telescope (8.2 m) located in Hawaii and is deliberately focused on the cloudy-halo and NOT on M81 galaxy (belonging to Ursa Major cluster).
