The Great Andromeda Galaxy (M31) | |||
| « Previous | Back to Astrophotography Gallery | Next » | |
M31, the Great Andromeda Galaxy, is the classic spiral galaxy, and the Milky Way's closest neighboring major galaxy. Andromeda lies a mere 2.54 million light years away, and is visible with the naked eye from a dark sky site. Two satellite galaxies are clearly visible, M32 above to the left, and M110 at the lower edge of the frame. Andromeda itself is estimated to contain one trillion stars. Three images (so far) are shown below, with the most recent, and hopefully the best, at top; the ones below are progressively older efforts. | |||
