  • The annual Geminid meteor shower has arrived

    The Geminid meteor shower will put on a dazzling show for skywatchers when it peaks overnight on Dec. 13-14. The Geminids are active every December, when Earth passes through a massive trail of dusty debris shed by a weird, rocky object named 3200 Phaethon. The dust and grit burn up when they run into Earth's atmosphere in a flurry of "shooting stars."
