Chalk up another fascinating revelation to the shuttle probram. Evidently the a recent shuttle experiment has come up with a logical explanation for the 1908 Tunguska Event in Siberia.
“…The mysterious 1908 Tunguska explosion that leveled 830 square miles of Siberian forest was almost certainly caused by a comet entering Earth’s atmosphere, says new Cornell research. The conclusion is supported by an unlikely source: the exhaust plume from the NASA space shuttle launched a century later.
The Tunguska Event, a massive explosion near the Tunguska River in what is now Krasnoyarsk Krai, Russia, at around 7:14 a.m.on June 30, 1908, has been the focus of intense speculation. Theories such as a natural H-bomb, a black hole, an antimatter explosion and even the crash of a UFO the size of Tokyo, have kept the buzz alive for the past hundred years .
The Cornell research supports the findings of a British astronomer who suggested in 1930 that the blast may have been caused by a small comet, composed specifically of ice and dust, thus leaving no recognizable trace of its presence. One theory proposes that the Tunguska object was a fragment of Comet Encke. This ball of ice and dust is responsible for a meteor shower called the Beta Taurids, which cascade into Earth’s atmosphere in late June and July – the time of the Tunguska event….”
