摘要

December brings one of the richest, most enigmatic meteor showers, the Geminids. Bright moonlight often spoils the annual show, but this year circumstances are ideal: The Geminids peak on the 13th, under a dark sky punctuated by a crescent moon that sets by twilight's end. Get away from city glow and you will see meteors streaking across the heavens all night long. Other major meteor showers require observers to wait until after midnight for the best fireworks, and the meteors are easy to miss because they're so fast. The Geminids are clearly different. They are in full swing by 9:30 p.m. and lope along at 22 miles a second, about half the speed of August's better-known Per-seids. In fact, the Geminids are so peculiar that they have forced planetary scientists to rethink their basic understanding of what a meteor shower is.
