Wish upon a falling star
Astronomers brace for meteor shower
THANIN WEERADET
The night sky will glow with streaks of light on Saturday and Sunday as meteors enter the earth's atmosphere, hopefully in a spectacular show.
The meteors are called the Leonids because they appear to radiate out of the constellation Leo.
A meteor, sometimes referred to as a "shooting star," is a particle from space. It usually ranges from the size of a grain of sand to that of a pea. A meteor appears when it enters Earth's atmosphere and burns up high overhead. Meteors can be seen at any time, but sometimes we get particularly spectacular meteor showers when the Earth enters clouds of particles several times each year.
Gary Kronk, from the American Meteor Society, said the Leonids are fast meteors and they leave lots of trains. They enter Earth's atmosphere travelling at speeds of over 158,000 miles per hour. For comparison, the fastest jet has a top speed of 2,190 mph and an orbiting spacecraft has an average speed of 20,000 mph.
The Leonids usually contain a large number of very bright meteors. The trains of these bright meteors can last from several seconds to several minutes.

LEONID SHOWER
National park open for a heavenly show
 |
Youngsters are excited with the appearance of meteors streaking throught the dark skies above Pakchong, in Nakhon Ratchasima, on November 19, 1998. |
Khao Yai National Park will open on Sunday night for people who want to watch the Leonid meteorite shower, which should peak early on Monday morning.
All rooms in the national park's shelters were booked out, but there were still camping sites available, assistant national park chief Saroj Praphan said.
He urged visitors to keep the area clean and to bring sweaters, because it can get cold there at this time of year.
Stargazers should look to the east after midnight on Sunday, preferably from somewhere without bright lights.
Weathermen say people in most parts of the country should have good visibility, except for the lower southern region.
