The annual Perseid meteor shower-worth checking out!

The annual Perseid meteor shower is expected to put on a good show this week for those willing to get up in the wee hours of the morning and wait patiently for the shooting stars. In North America, the best time to watch will be between midnight to 5 a.m. on Wednesday, Aug. 12, but late Tuesday night and also Wednesday night could prove fruitful, weather permitting. The Perseids are always reliable, and sometimes rather spectacular. The only things that puts a damper on the August show are bad weather or bright moonlight. Unfortunately this week, as the Perseids reach their peak Tuesday and Wednesday nights, the moon will be high in the sky, outshining the fainter meteors. Still, skywatchers around the globe will have a good chance of spotting the brighter meteors. Some already are enjoying the show which is already underway.

The Perseids are bits of debris from Comet Swift-Tuttle, which has laid down several streams of debris, each in a slightly different location, over the centuries as it orbits the sun. Every August, Earth passes through these debris streams, which spread out over time. "They are typically fast, bright and occasionally leave persistent trains," says Joe Rao, SPACE.com's Skywatching Columnist. "And every once in a while, a Perseid fireball will blaze forth, bright enough to be quite spectacular and more than capable to attract attention even in bright moonlight."
