On 30 June 1908 a mysterious explosion rocked the Jenissei portion of the Siberian forest. People living in the area observed a huge fireball that rose up high in the sky and never forgot the sight.
Russian scientist Kazantsev researched what he described as the Tunguska blast, going so far as trailblazing through the area in search of an impact crater that was never found. Trees in the area, though, were knocked to the ground from an epicenter which, unlike normal blasts, was more elliptical than spherical, following the original object’s trajectory.
Many wild theories have been suggested as to what caused the blast. Most prevalent among those have been microscopic black hole impact with the Earth, collision with a comet and a nuclear powered extraterrestrial vehicle losing control and crashing. Both are extremes, logic suggets a natural occurence.
What we know is this. At 7.00am on 30th June 1908 near the lower Tunguska River, Siberia, a large explosion occurred. The explosion was so massive that it caused damage 400 miles away, and was heard even further. Even the heat that came out from the explosion was felt hundreds of miles away. For several nights all over northern Europe, the sky glowed enough to light the street of London. At first it was assumed that a massive meteorite had collided with the earth.
