                        Astronomy Picture of the Day

    Discover the cosmos! Each day a different image or photograph of our
      fascinating universe is featured, along with a brief explanation
                    written by a professional astronomer.

     A full Moon is shown but with a much more detailed surface than is
       usually visible. Many craters, dark lunar mare, and light lunar
   highlands are discernable. Please see the explanation for more detailed
                                information.

   Explanation: What's different about this Moon? It's the terminators. In
   the featured image, you can't directly see any terminator -- the line
   that divides the light of day from the dark of night. That's because
   the featured image is a digital composite of many near-terminator lunar
   strips over a full Moon. Terminator regions show the longest and most
   prominent shadows -- shadows which, by their contrast and length, allow
   a flat photograph to appear three-dimensional. The overlay images were
   taken over two weeks in early April. Many of the Moon's craters stand
   out because of the shadows they all cast to the right. The image shows
   in graphic detail that the darker regions known as maria are not just
   darker than the rest of the Moon -- they are also flatter.
