The Geminid meteor shower is considered to be one of the best displays in the night sky, and this year will peak during the early hours of Friday.
Long, glowing arcs of white, yellow, blue, red and green will streak across the Northern Hemisphere sky.
You should be able to catch as many as 120 shooting stars an hour over the next night or so.
What is the Geminid meteor shower?
Most meteor showers are caused by comets - huge clumps of ice - but the Geminids are different.
The Geminid meteors originate from a rocky asteroid known as 3200 Phaethon.
Each year, the Earth passes through a trail of debris left by the asteroid as it orbits around the Sun.
When the debris hits our planet's atmosphere - at speeds of up to 70 kilometres per second - they burn up, producing streaks of light.
