Mid-December marks the peak of the annual Geminid meteor shower, where the skies come alive with bright and abundant shooting stars. Unlike most meteor showers, the Geminids are caused by debris from an asteroid, and can appear in multiple colors like white, yellow, green, red, and blue. You won't need any special equipment to witness this spectacular event, so mark your calendars for December 13-14 to catch a glimpse of the dazzling Geminids.
