meteor Rusia.. teguran Allah.

Meteor Russia 2012...

A meteor weighing ~10 tons and traveling at supersonic speed (54,000 kph or 33,000 mph) streaked over the Russian Ural Mtns. earlier today at 9:20 am local time (0320 GMT). About 400 injuries are reported, mostly due to broken glass and damage to a local factory.

A meteoride is a small piece of space debris – usually part of comets or asteroids – that is on a collision course with the Earth. When meteoroids enter the Earth's atmosphere they are called meteors. Most meteors burn up in the atmosphere, but if they survive the frictional heating and strike the surface of the Earth they are called meteorites. Currently, there is no technology to intercept such fast moving objects from crashing on earth.

Meteor Russia 2013...
Update: February 15, 2013 7pm PST

New information provided by a worldwide network of sensors has allowed scientists to refine their estimates for the size of the object that entered that atmosphere and disintegrated in the skies over Chelyabinsk, Russia, at 7:20:26 p.m. PST, or 10:20:26 p.m. EST on Feb. 14 (3:20:26 UTC on Feb. 15).

The estimated size of the object, prior to entering Earth's atmosphere, has been revised upward from 49 feet (15 meters) to 55 feet (17 meters), and its estimated mass has increased from 7,000 to 10,000 tons. Also, the estimate for energy released during the event has increased by 30 kilotons to nearly 500 kilotons of energy released. These new estimates were generated using new data that had been collected by five additional infrasound stations located around the world – the first recording of the event being in Alaska, over 6,500 kilometers away from Chelyabinsk. The infrasound data indicates that the event, from atmospheric entry to the meteor's airborne disintegration took 32.5 seconds. The calculations using the infrasound data were performed by Peter Brown at the University of Western Ontario, Canada.

"We would expect an event of this magnitude to occur once every 100 years on average," said Paul Chodas of NASA's Near-Earth Object Program Office at the Jet Propulsion Laboratory in Pasadena, Calif. "When you have a fireball of this size we would expect a large number of meteorites to reach the surface and in this case there were probably some large ones."

The trajectory of the Russia meteor was significantly different than the trajectory of the asteroid 2012 DA14, which hours later made its flyby of Earth, making it a completely unrelated object. The Russia meteor is the largest reported since 1908, when a meteor hit Tunguska, Siberia.

Kesan serpihan Meteorite…

A meteor streaked across the sky and exploded over Russia’s Ural Mountains with the power of an atomic bomb Friday, its sonic blasts shattering countless windows and injuring nearly 1,000 people.

p/s: kalau ujan meteor di malaysia rasanya kejap je lenyap semua....dunia hanya pentas ujian untuk manusia dlm mencari tujuan kehidupan yg sebenar.. apa peranan kita di dunia ini? kembali pada jalan Allah n ajaran muhammad saw selagi punya masa...bertaubatlah selagi pintu taubat masih belum tertutup rapat...
