The annual Geminid meteor shower peaks tonight. Astronomers say it's a promising year for this fine late-autumn shower, if skies are clear. Moonlight will not interfere. Meteor rates might exceed 120 per hour under dark-sky conditions. They'll appear to radiate from the bright stars of Gemini - Castor and Pollux - in the northeast after 8 p.m. Best around midnight. Geminid meteors are dust from an extinct comet, 3200 Phaeton.
