In A Really Cold Place – With a blinding flash and a booming shock wave, a meteor blazed across the sky over Russia’s Ural Mountains region Friday and exploded with the force of an atomic bomb, injuring more than 1,000 people as it blasted out windows and spread panic in a city of 1 million.

What was it like under that explosion? Watch this next video:

While NASA estimated the meteor was only about the size of a bus and weighed about 7,000 tons, the fireball it produced was dramatic. Video shot by startled residents of the city of Chelyabinsk showed its streaming contrails arcing toward the horizon just after sunrise, looking like something from a world-ending science-fiction movie.

The meteor over Russia entered the Earth’s atmosphere about 9:20 a.m. local time (10:20 p.m. EST Thursday) at a hypersonic speed of at least 33,000 mph (54,000 kph) and shattered into pieces about 30-50 kilometers (18-32 miles) high, the Russian Academy of Sciences said. NASA estimated its speed at about 40,000 mph and the energy released in the hundreds of kilotons.

The shock wave blew in an estimated 100,000 square meters (more than 1 million square feet) of glass, according to city officials, who said 3,000 buildings in Chelyabinsk were damaged. At a zinc factory, part of the roof collapsed.

Lessons had just started at Chelyabinsk schools when the meteor exploded, and officials said 258 children were among those injured. Amateur video showed a teacher speaking to her class as a powerful shock wave hit the room.

Yekaterina Melikhova, a high school student whose nose was bloody and whose upper lip was covered with a bandage, said she was in her geography class when a bright light flashed outside.

“After the flash, nothing happened for about three minutes. Then we rushed outdoors. … The door was made of glass, a shock wave made it hit us,” she said. (read more)
