Perseid Meteor Shower
PERSEID METEORS: I got to see about a dozen last night (early morning 8/11) in almost 2 hours. The meteors we'll see burn up in the night sky were released from Swift-Tuttle comet back in 1862! Some I couldn't see until I looked at my images on computer. I like this with the Big Dipper, which was super bright too, and clouds. I'll try again tonight at 0200 and hope it's clear, maybe going to the waterfront. I think some experts stack their images to get multiple meteors in one shot, or do multi-exposures. But at 40 secs per shot (with NR) the sky moves relative to the landscape.
From the web: The Perseid meteor shower comes along annually. The meteors are chunks of ice and rock that have flown off the back of the Swift-Tuttle comet which orbits our sun every 133 years and last passed through in 1992 (though the meteors we'll see this week were left behind in 1862).
As the Earth orbits through the debris field, our gravity sucks the meteors into the atmosphere at 132,000 miles per hour. Thankfully, they burn up 60 miles above the planets surface, said William Cooke with NASA’s Meteoroid Environment Office. Because of how the chunks burn up in the atmosphere we get a light show of shooting stars, or a meteor shower.
