Perseid Meteor Shower

Perseid Meteor Shower is about to "wash" the whole earth in a few days. As the VietNamNet says, is the nicest meteor shower of the year. VietNamNet come with a new photo of this year's meteor shower, which you can see on the right. The nice thing about natural wonders is that each time it happen, we have the chance to see new unbelievable images. Below is a excerpt from VietNamNet, which share the Vietnam's experience of the Perseid Meteor Shower, which has just passed over there:

The Perseids meteor shower comes annually, often from July 23 to August 22. People in the Northern Hemisphere, including Vietnam, can see the Perseids from August 12 at night to early morning August 13. During the peak time, one can see 60 to 100 meteors per hour. Different from the Delta Aquarids meteor shower on July 29, the peak time of Perseids is quite long. Dang Vu Tuan, Chairman of the Vietnam Young Astronomy Club, also said that this will be the largest meteor shower of the year, and should be very beautiful.

And here is a description from scientists:

The source of the shower is Comet Swift-Tuttle. Although the comet is far away, currently located beyond the orbit of Uranus, a trail of debris from the comet stretches all the way back to Earth. Crossing the trail in August, Earth will be pelted by specks of comet dust hitting the atmosphere at 132,000 mph. At that speed, even a flimsy speck of dust makes a vivid streak of light when it disintegrates--a meteor! Because, Swift-Tuttle's meteors streak out of the constellation Perseus, they are called "Perseids."
