NASA to enlist sky-watchers (Night of August 11, 2012) - Perseid Meteor Showers Count

from WWW. NASA. GOV :

Escape the heat of the waning days of summer for an evening of sky watching. The Perseid meteor shower peaks on the night of August 11 through the morning of August 12. Perseid rates can get as high as 100 per hour, with many fireballs visible in the night sky. A waning crescent moon will interfere slightly with this year's show, but viewing should definitely be worth a look!

On the night of Aug. 11-12, astronomer Bill Cooke and his team from the Meteoroid Environment Office at NASA's Marshall Space Flight Center will answer your questions about the 2012 Perseid meteor shower via an "Up All Night" live chat. A chat is available at www.nasa.gov/ The chat experts will be available to answer questions between the hours of 11 p.m. - 3 a.m. EDT, beginning the evening of Aug. 11 and continuing into the morning of Aug. 12.

Watch the Perseids! Live Video/Audio Feed

On the night of Aug. 11, a live video/audio feed of the Perseid shower will be embedded at NASA dot-gov. The camera is mounted at NASA's Marshall Space Flight Center in Huntsville, Alabama. During daylight, you'll see a dark gray box -- the camera is light-activated and will turn on at dusk. At night you'll see white points, or stars, on a black background.

About the Perseids

The Perseids have been observed for at least 2,000 years and are associated with the comet Swift-Tuttle, which orbits the sun once every 133 years. Each year in August, the Earth passes through a cloud of the comet's debris. These bits of ice and dust -- most over 1,000 years old -- burn up in the Earth's atmosphere to create one of the best meteor showers of the year. The Perseids can be seen all over the sky, but the best viewing opportunities will be across the northern hemisphere. Those with sharp eyes will see that the meteors radiate from the direction of the constellation Perseus.
