Chelyabinsk Meteor- In February, a massive, 12,000-ton meteor—the largest known to hit Earth since 1908—flew through the skies above Chelyabinsk, Russia at 60 times the speed of sound and shattered into pieces. The meteor caused damaged to about 7,200 buildings and caused nearly 1,500 people to seek medical attention for injuries. Luckily, no one was killed; luckier still, dozens of local residents caught the event on cam
First study results of Russian Chelyabinsk meteor published Nov 06, 2013 The meteor that exploded over Chelyabinsk, Russia in February 2013 that resulted in the damaging shock wave that sent over 1200 people to hospitals in the Chelyabinsk Oblast area that day," said Jenniskens. The explosion was equivalent to about 600 thousand tons of TNT, 150 times bigger than the 2012 Sutter's Mill meteorite in California.
Scientists have released microscopic images of fragments of the meteorite that hit central Russia in February. A team from the Ural Federal University was able to analyse some of the dozens of samples as soon as they were found. But the technique they used allowed them to assess the rock's chemical make-up at the microscopic level even as they snapped pictures of the fragments. This will provide extra information on the space rock's formation and journey.
