The Tunguska Explosion of 1908 was a powerful explosion that occurred near the Lower Stony Tunguska River in what is now part of Russia (Krasnoyarsk Krai, now Russia’s second largest Federal subject), at around 7:14 a.m. on June 30, 1908. Legendary for its destructive power, the cause of the explosion has been debated for decades, which was said to have caused the sky throughout Western Europe to glow green after impact. Recent scientific data seems to lend to the common theory that the air burst of a large meteoroid or comet fragment as much as 6 miles above the Earth’s surface was the cause of the destruction, but does evidence exist of a stranger, more out-of-this-world theory as to its cause?
