Members of the scientific expedition of the Siberian state foundation Tunguska Space Phenomenon have managed to uncover blocks of an extraterrestrial technical device, which crashed down on Earth on June 30th, 1908. In addition, expedition members found the so-called "deer" - the stone, which Tunguska eyewitnesses repeatedly mentioned in their stories. Explorers delivered a 50-kilogram piece of the stone to the city of Krasnoyarsk to be studied and analyzed.
Expedition was set off for Evenkia in July 2004 in order to solve the mystery behind the popular phenomenon known as Tungus meteorite.
The expedition, organized by the Siberian Public State Foundation “Tunguska Space Phenomenon” completed its work on the scene of Tunguska meteorite fall on August 9. It was the first expedition to the region since 2000. Guided by the space photos, the researchers scanned a wider territory in the vicinity of the Poligusa village for parts of the space object that crashed into Earth in 1908.
About Tunguska event
The Tunguska event was an aerial explosion that occurred near the Tunguska River in Siberia on June 30, 1908. The blast felled an estimated 60 million trees over 2,150 square kilometres. On this day, local residents observed a huge fireball, almost as bright as the Sun, moving across the sky. A few minutes later, there was a flash that lit up half of the sky, followed by a shock wave that knocked people off their feet and broke windows up to 400 miles away.
The explosion registered on seismic stations across Eurasia, and produced fluctuations in atmospheric pressure strong enough to be detected by the recently invented barographs in Britain. Over the next few weeks, night skies over Europe and western Russia glowed brightly enough for people to read by. In the United States, the Smithsonian Astrophysical Observatory and the Mount Wilson Observatory observed a decrease in atmospheric transparency that lasted for several months.
The size of the blast was later estimated to be between 10 and 15 megatons. Until this year members of numerous expeditions have failed to find any remains of the object that caused the event.
