1908 – the so-called “Tungus meteorite” fell and exploded in Eastern Siberia in the basin of the Pidkamyana Tunguska river.
On June 30, 1908, at 7:14 a.m. local time, the strangest event related to the study of space took place over the Southern Swamp near the Stony Tunguska River. Residents of the vast territory of Siberia, from Yakutia to the Urals, for several minutes watched a huge ball of fire in the sky, which shone brighter than the sun. The ball was moving slowly in a direction from southeast to northwest.
At approximately 7:15 a.m., the ball turned into a cylindrical pillar of fire, then a powerful explosion rang out. According to some estimates, the force of the explosion reached 40-50 megatons of TNT equivalent. It was heard 800 km from the epicenter. The blast wave felled a forest on an area of 2000 km², the glass of some houses was broken in a radius of 200 km. The seismic wave was registered by seismic stations in Irkutsk, Tashkent, Tbilisi, Yeni and other countries. For several days, an intense glow of the sky and clouds was observed from the Atlantic to central Siberia.
The event, which still worries scientists all over the world, was called the Tunguska phenomenon. After almost a whole century, science could not give a clear explanation for this strange phenomenon. At that time, about 100 versions of the event were put forward. Now there are even more of them.
Among the exotic versions:
– Collision with the Earth of a miniature black hole;
– the accident of an alien spacecraft;
– Nikola Tesla’s experiments with wireless electricity transmission;
– the hypothesis of an aerial nuclear explosion;
– a laser signal sent from the planetary system 61 Cygnus.
More realistic versions are:
– a normal fall of a meteorite, or a swarm of meteorites;
– the fall of the comet nucleus;
– explosion of a cloud of methane released as a result of volcanic activity;
– a big hurricane and a forest fire.
