Orionid meteor shower to streak across night sky this week

One of the best-known meteor showers of the year is returning to our skies this week, as the Earth passes through debris left behind by Halley's Comet.
The Orionid meteor shower is active from 2 October until 7 November and will peak overnight from 21 to 22 October.
The display occurs at around the same time each year as the Earth passes through a trail of dust and debris left behind by Halley's Comet.
