Astronomy Picture of the Day

   [1]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.

      [2]The featured image shows a full moon as constructed by images
    returned by the Lunar Reconnaissance Orbiter (LRO). Specifically, the
   images just to the bright side of the lunar terminator are used, which
   shows the lunar surface in great detail. Please see the explanation for
                         more detailed information.

   Explanation: What's different about this Moon? It's the [8]terminators.
   In the featured image, you can't directly see any [9]terminator -- the
   line that divides the light of day from the dark of night. That's
   because the image is a digital composite of 29 near-terminator lunar
   strips. Terminator regions show the longest and most [10]prominent
   shadows -- shadows which, by their contrast and length, allow a flat
   photograph to appear three-dimensional. The [11]original images and
   data were taken near the [12]Moon by NASA's [13]Lunar Reconnaissance
   Orbiter. Many of the Moon's [14]craters stand out because of the
   [15]shadows they all cast to the right. The image shows in graphic
   detail that the [16]darker regions known as maria are not just darker
   than the rest of the [17]Moon -- they are flatter.
