Eyes on the sky watch the unpredictable Draconid meteor shower

Meteor showers — nature’s superlative fireworks displays — occur when Earth’s orbit intersects a trail of debris left behind by a comet. Meteoroids from the comet stream collide with Earth’s atmosphere and ignite, punctuating the night sky with a cascade of shooting stars. Scientists can accurately forecast the timing of meteor showers using the principles of celestial mechanics; however, the intensity of the Draconid shower, which occurs every October, has proved notoriously hard to predict.
