The moon rises behind trees in Bucharest May 5, 2012. A "super Moon" lights up Saturday's night sky in a once-a-year cosmic show, overshadowing a meteor shower from remnants of Halley's Comet, the US space agency NASA said. The Moon seems especially big and bright since it reaches its closest spot to Earth at the same time it is in its full phase, NASA said. [Photo/Agencies]
