Perhaps it was the Italian scientists can unravel the mystery of Tunguska, which remains unsolved since June 30, 1908, at 07:14 am when a mysterious object oblong, brighter than the sun crossed the sky and rushed to the area of the Stony Tunguska — in Central Siberia where Taiga goes into the swamp, and the soil is still icy, at least 8 months of the year, writes La Repubblica.
The newspaper reminds that in the Stony Tunguska River, tributary of the Yenisei River, was the fact that even after a century no one could understand. Was a hit, the biggest and most destructive force in our era: a blow up a huge column of fire, which reached 15 km in height. The roar was heard hundreds of miles from the epicenter.
Now around the Tunguska mystery more controversial than the truth. Who killed the taiga? Who killed thousands of reindeer and forest in the territory, comparable to the area of the Italian region of Marche? Stone asteroid? Ice comet? Or, as suggested hunters UFOs, alien spaceship that exploded during the launch from Earth? Scientist Leonid Kulik, the first explorer who in 1927 dared to visit the Great Dead Earth, suggested that the cause of the phenomenon could be a meteorite made of iron and nickel. For 12 years, he carefully studied the terrain. But have not found a single gram of this meteorite.
During the conference, a group of scientists in the Russian Academy of Sciences, led by Professor of Physics at the University of Bologna, Giuseppe Longo, reported that it had found traces of a possible crater formed by the impact: Ceco lake, 8 km from the epicenter of the explosion. Longo and his colleagues hope to find a piece of the space object. Longo and his team engaged in the Tunguska catastrophe in 1991: Gradually they began to come to the conclusion that the explosion in the atmosphere of an asteroid or comet led to the formation of the lake next to the river Checo Kimchu. The lake elongated, slightly elliptical shape, is very different from the typical form of other Siberian lakes. Sometimes simple enough intuition to uncover the mystery of the most intricate, the newspaper stresses.
Note that, despite the fact that since the events took place a hundred years old, it still raises many questions for scientists and attracts the attention of the public. It is the only large-scale human memory space catastrophe, comparable in its effects to a nuclear strike. If the Tunguska body blow came in the densely populated area, the number of victims could be measured in millions.
However the nature of the fallen in the Siberian taiga cosmic body is still not entirely clear, it is not clear and that for which of our space "neighbors" — asteroids, comets and other bodies, should ensure humanity to avoid a repeat of the disaster. The study of the Tunguska catastrophe allows you to see all of the environmental and geophysical effects of the fall of the cosmic body, to draw conclusions about the possible short-and long-term consequences of these events.
