The moon, on its way to being totally eclipsed, is seen with the Chrysler Building in the foreground in New York, Tuesday, Dec. 21, 2010. A total lunar eclipse occurs when the Earth casts its shadow on the full moon, blocking the sun's rays that otherwise reflect off the moon's surface. Some indirect sunlight still pierces through to give the moon its eerie hue. (AP Photo/Seth Wenig)
