On October 21, the dazzling Orionid meteor shower is set to light up the night sky. It's not just known for its streaks of shooting stars, but it may also accidentally surprise spectator with a single exceptionally bright star that burns brighter than all the others. It expected to be visible every year from around October 2 through November 7, when the Earth passes debris from Halley's Comet, which last visited Earth in 1986. The best time to catch the Orionid meteor shower is from 2 am to early morning on October 21. During that time, you might see 10 to 20 meteors per hour. [Photo/CCTV News]
