Last night, and later tonight, skywatchers around the world will be treated to views of this year's so-called "supermoon," the largest full moon of the year. Today, on November 14, at 6:20 am Eastern time, the moon approached within 356,500 km (221,500 mi) of Earth, in what is scientifically known as a perigee-syzygy of the Earth-Moon-Sun system (perigee: closest point of an elliptical orbit; syzygy: straight line made of three bodies in a gravitational system). Though the moon does appear larger than normal, the size difference is so small that a casual observer would probably never notice. Nonetheless, photographers across the globe set out to capture the event, and collected here are 21 of the most super images of this year's supermoon. If your skies are clear, be sure to look up around moonrise tonight.
