Night owls get a light show tonight—the Orionid meteor shower peaks in the overnight hours. Things should pick up about midnight, but the best viewing will probably be just before dawn. The Earth is passing through debris from Halley's Comet, though the comet itself won't be making a pass near us until 2061, explains ABC News. If clouds spoils things in your area, NASA is running a livestream of the Orionids and a related chat here, starting at 11 Eastern. (More Halley's Comet stories.)
