It’s actually going on right now—though it will continue until Thursday. The best time to see the shooting stars is between 1 and 3 AM your local time, so bundle up (especially if you’re in my snowy area, or an even colder one!) and go take a peek! The Geminids are the only meteor shower that is not caused by a passing comet, and they are considered slow-moving. You can find out all about them here.
