In 1908 an explosion occurred in Tunguska, Siberia flattening trees and scorching hundreds of square miles. The energy from the explosion was felt around the globe and estimated to be 1,000 times as powerful as the bomb dropped on Hiroshima, Japan and about one-third the power of the Tsar Bomba, the largest nuclear weapon ever detonated. Many years later an expedition to the Tgunska site revealed no evidence of meteorite or comet impact.
