Announcing the mystery of the Tunguska explosion

Scientists at the University of Bologna and Trieste have published the latest findings related to the mysterious explosion in the Tunguska region of Russia's Siberia, almost a century ago.

On June 30, 1908, an explosive blast of thousands of atomic bombs dropped by the US on Hiroshima occurred in Tunguska region, clearing 60 million pine trees within 2150 km ² . The explosive sound could even be heard from 1 thousand kilometers away. Many assumptions have been made, in which the most acceptable opinion is that a meteor with a diameter of 5 to 10 km collided with the Earth. However, one cannot find any trace of the meteorite.

99 years after the explosion, Italian researchers found signs that it was true that a meteorite had fallen to Earth. Studies at Lake Cheko, 500 meters in diameter at the center of the explosion, showed that the lake could be created by a meteorite with a diameter of 50 to 80 meters falling to Earth after a a large meteorite, or a comet tail that explodes in the atmosphere, at a height of 5 to 10 km in the sky of Tunguska.

By the most advanced search and exploration facilities on the bottom of the lake, scientists have found traces of lake formation, suggesting that the age of the lake is very young, not already available. 5 thousand years old as previously assumed hypothesis of many American and Russian scientists . The oval shape of the lake adds to the power of Italian scientists' assumptions about the fall of a meteorite, which has been strengthened by their new discoveries.

The newly discovered discovery, if proven and acknowledged, will shed light on one of the biggest mysteries of a celestial collision with Earth a century ago.
