The event was the long-awaited lover of astronomy because of its light. "Rain is one of the Perseid meteor meteor shower expected eight appearance every year," said Judge L. Bosscha Observatory Director Sluggish. Perseid always appear every year in August.
The name comes from the name Perseid constellation Perseus because the meteor shower was as if coming from the direction of the constellation. Meteor velocity is approximately 60 kilometers per hour, and has a flash of bright meteors with long light.
This meteor shower occurs because the earth every year, according to the path, hitting the residual dust from the tail of comet Swift-Tuttle. Comet was estimated to be very large, with a diameter of 200 kilometers and it took 130 years revolves around the Sun. As a result a lot of dust tail and about the earth's atmosphere look like grains of sand in the sky that lights up.
This year the Perseid meteor shower took place on 7 to 15 August 2010, where a peak in 12 to 13 August. Tuesday last week, NASA succeeded in capturing images fireball (Fireball) that appears when the Perseid meteor shower in Paint Rock, Alabama.
"The ball of fire was so good start to see the Perseid meteor shower circuit this year," said NASA spokeswoman Janet Anderson. The institute identified the meteor was 2.5 centimeters in diameter and moving with a speed of 215 thousand kilometers per hour. With astonishing speed, the tail raises meteor fire along 104.6 miles, before was burned at an altitude of 90 kilometers. "The light was six times brighter than Venus," said Anderson.
Based on the observation of the International Meteor Organization (IMO) the last few years, these peak periods of rain on the night of August 12 to 13 to 100 meteors per hour. In the last two decades, there is even 150-400 meteors per hour as the Earth passed through the high density regions in the flow of dust.
IMO citing simulations made Jeremie Vaubaillon and Mikhail Maslow. Both experts indicated that this year we may face a "period of scattered dust" when the comet passed the Sun in 441-year period, 1479 and 1862.
Space.com columnist, Joe Rao also mentions this month is the best time to observe the Perseid meteor shower. "Population of Indonesia from Aceh to Papua can see in the sky toward the northeast," said senior researcher of astronomy and astrophysics from the Institute of Aeronautics and Space, Thomas Djamaluddin. Peak of the meteor shower will take place at 2:00 a.m. to 5:00 pm local time.
According to Thomas, the event was a meteor shower can be seen with the naked eye without the need to use a telescope alias. "Condition, sunny skies, light pollution is not disturbed, and field of view is not obstructed," he said. Residents in all regions of Indonesia could see 50-80 meteors per hour of rain, or 1-2 meteors per minute. Size as grains of sand, he added, that would prevent dangerous because it will be burned in the atmosphere.
