Every year in autumn, our planet passes through a ribbon of space-debris left behind by Halley’s Comet, and Earth’s atmosphere colliding with this trail of ice and dust provides an impressive annual light show called the Orionids meteor shower. The first Orionid shooting stars are already showing up in the sky, and the show will continue through the first week in November or so, but the peak of the meteor shower will happen in the early morning between October 21 and 22.
