The Hundred-Year Mystery The burning chunk of rock struck Siberia on Jwith a force 1,000 times more powerful than the atomic bomb dropped on Hiroshima. Daniil E Khrennikov, On the possibility of through passage of asteroid bodies across the Earth’s atmosphere. It has taken researchers over a century to identify the extraterrestrial object-but in a recent paper, geoscientists revealed that the culprit was indeed a meteoroid.The study shows a glancing impact is a possible solution there’s no way to prove it’s the real cause. The event is now widely attributed in the astronomical community to the detonation of icy material from a comet in Earths atmosphere. Something travelling that fast has collided with the earth before - in June of 1908. The rapid compression of air near the asteroid would be enough to make the impact region observed. The celestial visitor has been named DA14 and is expected to travel at speeds of about 8 miles (13km) a second. It could, in any case, be orbiting the sun right to this day. If the object had a shallow effect on the atmosphere, coming to inside 10 kilometers of the Earth’s surface, it would have remained, to a great extent, unscathed and came back to space to enter the near sun to this day. But now, 105 years later, scientists have revealed that the Tunguska devastation was indeed caused by a meteorite. They found that the most probable situation is an iron asteroid around 200 meters in size. Instead, it glanced off Earth’s atmosphere.įor this study, scientists studied the conditions of through passage of asteroids with diameters 200, 100, and 50 m, consisting of three types of materials – iron, stone, and water ice. There's also no record of the lake existing before 1908, but it's also true that the region was poorly explored at the time and not all scientists agree with this theory.A new study shedding light on the event again, suggests that there are no fragments because the asteroid didn’t fragment after all. Lake Cheko is unusually deep for a region characterized otherwise by shallow ponds, formed by melting soil. In 2007, Luca Gasperini and his research team of the University of Bologna proposed that the small Lake Cheko may have formed by the impact of a fragment of the Tunguska meteorite. A chemical analysis of the metallic and silicate spherules is not possible, as elements from the magmatic rocks forming the bed of the Stony Tunguska contaminate the samples. Orbital elements of the Tunguska meteoroid depending on the altitude of the radiant. The nature of this cosmic body remains unclear. This idea is supported by the reports describing a fireball descending on the taiga, the presence of impact-related minerals like nanodiamonds, metallic and silicate spherules in sediments, the mapped distribution and direction of the flattened trees, pointing away from a single explosion site, and a temporal link between Tunguska and the Taurid swarm. To this day, the accepted theory explaining the Tunguska Event remains a cosmic body entering Earth's atmosphere, with a subsequent midair explosion and an airburst flattening more than 80 million trees. According to the observations made by the Ket people, the bright night phenomenon at Sulomay precedes the Tunguska Event by at least one night, and both phenomena may not be connected at all.
Most scientists believe that the glowing clouds and bright night phenomenon reported after the event were the result of meteoric dust, scattered by the explosion of a celestial body in Earth's atmosphere around the globe. An area of uprooted trees facing east, likely flattened by the shock wave traveling before a celestial body entering Earth’s atmosphere, could fit this description.īut there are also some inconsistencies emerging from those accounts with previous models. Johns Stone: A possible fragment of the 1908 Tunguska meteorite. Sulomay is also the farthest known place where the wind was strong enough to fell trees, as some accounts describe how "deer fled away", carried by the wind. Anfinogenov J, Budaeva L, Anfinogenova Y.
