Look up when the sun goes down Wednesday night and Thursday morning for one of nature's best shows of the year.

The Perseids meteor shower (search) is set to arrive.

Meteor forecaster Bill Cook of Marshall Space Flight Center (search) in Alabama said that as long as people are away from city lights and have clear skies, they should be able to watch the meteors.

No special equipment, like binoculars or telescopes, should be needed.

NASA officials said the show will reach its peak in pre-dawn hours Thursday.

The meteors are called the Perseids because they appear to radiate from the constellation Perseus (search). The light is caused when bits of dust hit Earth's atmosphere at 108,000 mph.
