A clear, Friday night in Ontario, Canada. A flaming fireball lights up the night sky as it streaks to Earth. It could carry with it secrets about the origins of our Solar System or evidence of life on other planets. But in order to study it, scientists first need to find it. At the University of Western Ontario, planetary scientists capture the entire event using a sophisticated network of specialized cameras, radar and listening equipment aimed at the heavens. This event may be the best documented meteorite fall in history. Now, scientists plot a search area and mount a team to hunt for it. The race is on, to find Earths latest visitor.

Parallel universes, strange hidden worlds, where an alternative reality exists have haunted science fiction for decades. Parallel universes sound like a myth, but a surprising number of leading scientists believe they are real. National Geographic delves into the mysterious science of other universes and discovers that many of physics most cherished theories actually predict that there are other universes beside our own. But what are they like? Could we ever visit them? And if we did, who or what would we meet? The reality is weirder than any science fiction.
