   Two images of a partial lunar eclipse are shown. On the left the image
    is overexposed everywhere except the bottom right where the eclipsed
    part of the Moon is visible. On the right image most of the image is
     normally exposed but the bottom right part is dark. Please see the
                 explanation for more detailed information.

   Explanation: What's happened to the Moon? Within the last day, part of
   the Moon moved through the Earth's shadow. This happens about once or
   twice a year, but not every month since the Moon's orbit around the
   Earth is slightly tilted. Pictured here, the face of a full Hunter's
   Moon is shown twice from Italy during this partial lunar eclipse. On
   the left, most of the Moon appears overexposed except for the eclipsed
   bottom right, which shows some familiar lunar surface details. In
   contrast, on the right, most of the (same) Moon appears normally
   exposed, with the exception of the bottom right, which now appears
   dark. All lunar eclipses are visible from the half of the Earth facing
   the Moon at the time of the eclipse, but this eclipse was visible
   specifically from Europe, Africa, Asia, and Australia, clouds
   permitting. In April, a total solar eclipse will be visible from North
   America.
