Running with a supermoonA runner makes his way along a trail on a butte in front of the "supermoon" over Papago Park in Phoenix on May 5. This full moon is the biggest and brightest of 2012, thanks to the orbital mechanics of the moon's phases and its orbit around Earth. In this photograph, the effect is heightened dramatically through the use of a telephoto lens.
