The moon is seen during a total lunar eclipse from New York, Tuesday, Dec. 21, 2010. A total lunar eclipse occurs when the Earth casts its shadow on the full moon, blocking the sun&#39;s rays that otherwise reflect off the moon&#39;s surface. Some indirect sunlight still pierces through to give the moon its reddish hue.  &#40;AP Photo&#47;Seth Wenig&#41; <span class=meta>(AP Photo&#47; Seth Wenig)</span>
