It's time for the Geminid meteor shower, one of the strongest of the year. The Geminids peak this weekend and are visible through mid-December. The fireballs tend to be yellow in color and can be seen across the globe, but the best viewing happens in the Northern Hemisphere. Meteor showers appear when fast-moving space rocks enter Earth’s atmosphere and burn up, leaving behind fiery tails. To enjoy the show, venture away from city lights and avoid looking at your phone. The meteors will appear as tiny glows streaking across the sky.
