Tonight the Orionid meteor shower will be most readily seen in the night sky. What is the Orionid Meteor Shower? If you've heard of Halley's comet, well when Halley's travels through our inner solar system it drags along space dust and debris and can even knock other meteors and debris out of it's path. The trail of those things being displaced in the wake of Halley's comet is what we can see in the night sky. The folks over at MeteorShowers.org have a great interactive model that shows you what the trail of debris looks like and from different angles and perspectives.
