Skywatchers are getting set for the Geminid meteor shower, which this year peaks in the late evening of Monday, Dec. 13, and on the following morning.

The Geminids are considered among the year’s best and most reliable meteor showers, according to the National Aeronautics and Space Administration, capable of delivering scores of shooting stars per hour during their peak. But this year, some of the brilliant streaks of light the meteors leave behind when they race across the night sky could be washed out by light from a moon that is 78% full.
