The object in question was between 100 to 200 meters in diameter, and although it created widespread destruction beneath it, it left no traces of itself as it passed through the atmosphere. The Tunguska event was an explosion that occurred on 30 June 1908, in the Siberian region of Russia, possibly caused by a meteor air burst.The event has inspired much speculation and appears in various fictional works. Asteroid: A rocky object that orbits the sun and has an average size between a meteoroid and a planet. A meteoroid, especially one that has hit Earths surface. 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. It flattened 830 square miles (2150 sq km) of Siberian. Sergei Karpov, a leading scientist at the Kirensky Physics Institute in Krasnoyarsk, the Tunguska event was created by a space object, and it was an asteroid body that passed through Earth’s atmosphere and managed to continue to a near-solar orbit. Expert Answers: Bottom line: The Tunguska explosion on June 30, 1908, was the largest asteroid impact in recorded history. However, a new theory may finally explain the hundred-year-old mystery. THE deduction of Cowan et al.1, from their radiocarbon measurements of tree rings, that the Tunguska meteorite could not have been made of anti-matter has.

But despite the numerous theories, there has been little to no evidence at all to support the existence of a space object causing the destruction in Siberia. It’s a long way to come for a fly-by, but then this is no ordinary lake.Theories proposed that a meteor exploded in the atmosphere, leveling the ground beneath it, or a meteorite striking the surface but burying itself so deep that no one ever found it, or even a comet composed mainly of ice disintegrating, creating widespread destruction. This paper contains basic data relating to the Tunguska Meteorite (TM) as late as 1996, including flight and explosion of a giant bolide in Siberia on 30. So the pilot dips down and we make a second lap, coming in even lower. Unfortunately, it’s too late in the year to land near Cheko – the permafrost has thawed, turning the surrounding area into a swamp. The Tunguska event was an explosion thought to be caused by a large meteoroid. The other passengers – a local family and a geologist prospecting for gas in the area – seem bewildered by my interest in this remote spot. It’s just a short hop in a helicopter, but hiring one costs a princely $4000 an hour, so instead I manage to convince the pilot of a scheduled flight connecting local villages to make a slight detour over the lake. Pine and larch forests stretch as far as the eye can see in every direction, a view interrupted only by the serpentine wend of the Kimchu river, which runs like an artery through this wilderness.įrom the nearest town, Vanavara (population 3000), there are three ways to reach Lake Cheko: a two-day journey up the river, an even longer trek through swamp and forest, or by air. The nearest city, Krasnoyarsk, is some 600 kilometres to the south-west. This is truly the middle of nowhere: from London it has taken me three flights, two days and a pinch of luck to get here. Chelyabinsk was the largest meteoroid strike since the Tunguska event of 1908, and, thanks to modern technology from consumer video cameras to advanced laboratory techniques, provides an. I’M PEERING out the window of a Soviet-era Mi-8 cargo helicopter that’s hovering 50 metres above Lake Cheko, deep in the heart of the Siberian taiga. Video: A visit to the site of the Tunguska explosion The Tunguska event (Tunguska blast, Tunguska meteorite) was a massive aerial explosion of some sort that occurred in 1908 over a region in western Siberia, Russia. The explosion registered on instruments worldwide and led to noticeable atmospheric effects for months afterward, as well as leveling trees and burning land over a wide area.
