12/30/2013 - Chelyabinsk meteorite hit the Earth like a warning shot fired from space - the meteorite is providing invaluable information to help protect against larger rocks that might pose a serious threat to Earth
11/07/2013 - Scientists reveal the full power of the Chelyabinsk meteor explosion - at its most intense, meteor fireball glowed 30 times brighter than the sun causing skin and retinal burns, say researchers
One of the best-known recorded impacts in modern times was the Tunguska event, which occurred in Siberia, Russia, in 1908. The 2013 Chelyabinsk meteor event is the only known such event to result in a large number of casualties, and the Chelyabinsk meteor is the largest recorded object to have encountered the Earth since the Tunguska event
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.
