Massive Meteor Explosion Detected

The meteor explosion went unnoticed and scientists have only recently been able to pinpoint the explosion in the atmosphere over the Bering Sea, between Alaska and Russia, in December of last year.

According to NASA, the blast was pinpointed by triangulating low-frequency noises from infrasound stations around the world.

The meteor estimated to weigh 1,400 tons and just several meters wide, exploded with 10 times the energy released by the atomic bomb that was dropped on Hiroshima. Explosions this size are expected only two or three times a century. It was the biggest since the fireball over Chelyabinsk in Russia six years ago.

Around noon local time on December 18th, the meteor entered the atmosphere at a speed of 72,000 mph on a steep trajectory, exploding 16 miles up.

Military satellites picked up the blast last year and the US Air Force notified NASA of the event.
