Russian scientists have analyzed a lot of data on this incident and conducted its own investigation into the matter. Their work shows that the explanation of this puzzle is more obvious than we hitherto thought.
On the morning of 30 June 1908 at 7:17 on the Siberian Tunguska River Podkamienna a huge explosion. She had the strength of approx. 50 megatons, roughly as much as the largest thermonuclear bomb detonated by a man. This can be compared with as many as 185 bombs dumps Hiroszimę.Eksplozja knocked on 80 million trees in the taiga, on the surface of 2,000 km sq., On a much larger area sparked fires. The shock wave circled the Earth twice. Even the next day after the crash at 22:00, among others, could read a book in France, using the unusual aurora lights hovering over the horizon.
In London there was an earthquake, and Russia accused the Japanese of starting a war. What exploded 112 years ago? One hypothesis is that it was a comet, composed mainly of dirty ice that does not hit the Earth, only touched the atmosphere and flew away. The move provoked an unimaginable shock wave, however, the effects of which can still be seen on old photographs from Siberia. The researchers explain that observed in Europe “white nights” could be due to scattering of sunlight on her braid.
This riddle suggests a new study conducted by researchers from the Institute of Physical. P. N. Lebedev in Moscow and the Siberian Federal University. They exclude the possibility of an asteroid hitting the Earth built of iron or stone, because it would cause much greater damage, may perhaps even global. It not without significance here is the fact that today not discovered fragments of meteorites, which can be confirmation of this theory.
Scientists are almost certain that we are dealing with the transition by the Earth’s atmosphere of a small comet built from ice or iron asteroid. Its impact on the atmosphere vaporizing part of the material of the core and wherein the shock waves caused, and the remaining fragments further flown into the pit space. Therefore, they can not be found on the Earth’s surface.
The researchers calculated that the space rock had a diameter of 100 to 200 meters and passed through the Earth’s atmosphere at a minimum altitude of 10-15 kilometers at a speed of approx MOBILETECH. 20 kilometers per second. The property was originally the weight of approx. Three million tons, but after hitting the Earth’s atmosphere had lost half the weight. This fact, however, did not affect the trajectory of his flight, which he continued.
According to Don Yeomans of NASA’s meteorite similar to the 112 years before it happens once every 300 years, so sooner or later awaits us replay of Tunguska. The problem is that no one knows where it might happen. World space agencies formed so more and more advanced technologies that will enable us to detect even the smaller space rocks that threaten our planet. Perhaps faster to detect them ever make in advance to prepare for such events, so we do not limit the damage caused by.
