   Explanation: Why is the Moon on top of this building? Planning. It took
   the astrophotographer careful planning -- including figuring out
   exactly where to place the camera and exactly when to take the shot --
   to create this striking superposition. The single image featured was
   taken in the early morning hours of November 19, near the peak of the
   partial lunar eclipse that was occurring as the Moon passed through the
   Earth's shadow. At this time, almost the entire Moon -- 99.1 percent of
   its area -- was in the darkest part of the Earth's shadow. The building
   is the Gran Torre Santiago building in Chile, the tallest building in
   South America. Although the entire eclipse lasted an impressive six
   hours, this image had to be taken within just a few seconds to get the
   alignment right -- the Earth's rotation soon moved the building out of
   alignment. The next Earth-Moon eclipse will be a total eclipse of the
   Sun that will occur on December 4 -- but only be visible from the
   bottom of our world.
