   The Earth Science Picture of the Day (EPOD) highlights the diverse processes   
   and phenomena which shape our planet and our lives. EPOD will collect and   
   archive photos, imagery, graphics, and artwork with short explanatory   
   captions and links exemplifying features within the Earth system. The   
   community is invited to contribute digital imagery, short captions and   
   relevant links.

      The  Andromeda Galaxy (M31) is considered the  most distant   
      object that we can detect with the  unaided eye. If you live in the   
      Northern Hemisphere and have never seen a galaxy, other than our   
       Milky Way, you owe it to yourself to venture into the countryside   
      on a clear, moonless autumn evening and look to the northeast. Between   
      the stars is the  asterism of the  Square of Pegasus and the   
      constellation of  Perseus, a very faint glow will appear in the   
      constellation of  Andromeda. You may need to use  averted vision   
      to see it. If you still can’t spot it, grab a pair of binoculars.   
      
      Of course, don’t expect to see anything that resembles the remarkable   
      images above, captured from the  New Forest Observatory.   
      Nevertheless, just being able to discern this  distant smudge (some   
      2.5 million light years away) is thrilling. The light we see when we   
      gaze at M31 began its path to our eyes about the time that North   
      America and South America were linked by the  Isthmus of Panama and   
      around the time our ancestors were starting to stand upright. We can   
      see it with the naked eye not only because it’s relatively close by   
      (one of the Milky Way's nearest galactic neighbors), but because it’s   
      huge -– 220,000 light years across, holding perhaps a trillion stars.
