Meteor Shower Puts on a Show - CBS News: "The annual Perseid meteor shower put on quite a show Tuesday night for stargazers from Europe to California.
Astronomers predicted that as many as up to 100 meteors per hour would streak across the sky during the shower's peak.
The display was visible for many lucky enough to have clear skys in the northern hemisphere, but in North America, the best time to watch was just before dawn Wednesday.
Astronomers said the best way to ensure a good view was to move away from cities and other heavily lit areas.
The Perseid shower occurs every summer when the Earth's orbit crosses the path of debris thrown off by Comet Swift-Tuttle."
