A supermoon is pictured at the beginning of a total lunar eclipse over Cairo, Egypt, September 28, 2015. Sky-watchers around the world are in for a treat Sunday night and Monday when the shadow of Earth casts a reddish glow on the moon, the result of rare combination of an eclipse with the closest full moon of the year. The total "supermoon" lunar eclipse, also known as a "blood moon" is one that appears bigger and brighter than usual as it reaches the point in its orbit that is closest to Earth. Photo by Amr Sayed
