The summer's best meteor shower peaked on the weekend of Aug. 12-13. Even though the Perseids were hampered by a bright, full moon they were something to behold!

The Perseids have been observed for about 2,000 years. The source of the annual meteor shower is the debris trail left behind comet Swift-Tuttle. Each year in August, the Earth passes through a cloud of the comet's debris. These bits of ice and dust burn up in the Earth's atmosphere.

Most of the Perseid meteors that we observe now were ejected from Swift-Tuttle about 1,000 years ago. Marshall's meteor camera network captured some of the meteors or "shooting stars" during the peak.

On the night of Aug. 12-13, NASA astronomer Bill Cooke and his team from the Meteoroid Environment Office at Marshall Space Flight Center observed the peak of the Perseid shower via a live Web chat.
