Perseid Meteor Shower Light Show Peaks Tonight

by Denise Chow, SPACE.com

 

In a double weekend treat, one of the most well-known and reliable meteor showers — the Perseid meteor shower — will reach its peak overnight Friday (Aug. 12) as the International Space Station flies across the sky above many U.S. cities.

The annual Perseid meteor shower returns this week, but is expected to hit its peak activity in the overnight hours of Friday and Saturday (Aug. 13). While the full moon of August may interfere with the meteor display, the best time to catch the pretty light show (weather permitting) is during the predawn hours, especially on Saturday morning, experts at NASA advise. 

And if you're looking skyward before dawn this week, you might also be able to glimpse the space station overhead. [Photos: Amazing Perseid Meteor Shower Displays]

NASA is inviting the public to participate in a Perseids webchat and "all-night" meteor shower viewing party, hosted by astronomer Bill Cooke and his team from NASA's Marshall Space Flight Center in Huntsville, Ala. The webchat will begin at 11:00 p.m. EDT (0300 GMT) on Friday (Aug. 12) and will last until 5:00 a.m. EDT (0900 GMT) on Saturday (Aug. 13).

The Perseid meteor shower occurs every year as Earth passes through a stream of dust particles and debris from the Comet Swift-Tuttle. As these specks of comet dust hit the top of Earth's atmosphere at speeds of up to 140,000 miles per hour (225,000 kilometers per hour), they are heated and form bright meteor streaks that can be seen across the sky.

These meteors stream out of the constellation of Perseus, which is how the meteor shower got the name "Perseids." [Top 10 Perseid Meteor Shower Facts]

Seattle Man Captures Night Sky in 37,440 Exposures

Nick Risinger has always gazed up at the sky. But last year the amateur astronomer and photographer quit his day job as a Seattle marketing director and lugged six synchronized cameras about 60,000 miles to capture an image of the entire night sky.

The details of the Scorpius constellation, right, and the Milky Way are seen in this photograph, which is taken from an image Nick Risinger produced of the entire night sky made up of a composite image of more than 37,000 exposures.

Nick Risinger has always gazed up at the sky. But last year the amateur astronomer and photographer quit his day job as a Seattle marketing director and lugged six synchronized cameras about 60,000 miles to capture an image of the entire night sky.

Risinger, 28, set up his rack of cameras in high-elevation locales in the Western U.S. and South Africa, timing photo shoots around new moons when nights were long and dark. He programmed his six cameras to track the stars as they moved across the sky and simultaneously snapped thousands of photos.

He then stitched 37,440 exposures together into a spectacular, panoramic survey sky that he posted online two weeks ago. The photo reveals a 360-degree view of the Milky Way, planets and stars in their true natural colors. Viewers can zoom in on portions of the 5,000-megapixel image to find Orion or the Large Magellanic Cloud. http://media.skysurvey.org/interactive360/index.html
