Tunguska Explosion is one of the most mysterious and widely studied phenomena of the past century. Most experts have argued that the Tunguska event should have been a massive meteorite, comet or asteroid that hit the earth. Although the theory has the most support, the impact crater has not been found, leaving the Tunguska event a big mystery. Here are the top 10 Mysterious Facts about Tunguska Explosion<a name=\'more\'></a> : (1) At dawn on June 30, 1908, among the sleeping Russians in the Tunguska region of Siberia, there were couples hugging, sleeping children, and elderly people talking in their sleep. Outside, the gray black sky suddenly wind, the wind mixed with a huge noise. The wind stopped suddenly, and after a moment of silence there was an extraordinary noise from below, first like a train rolling along the track, then like a cannon five or six minutes later. After fifty or sixty unusual sounds, the sound gradually subsided, followed by a short but regular pause. Then the wind began to blow again. (2) An explosion like a cannon was heard, and a burning monster, with a long firework tail, swept across the sky from south to north and disappeared beyond the horizon. More than a minute later, people heard many times from the distance, clear roar, the earth began to tremble. Three powerful explosions were then felt. (3) Tunguska is surrounded by dust and smoke, clouds of fire and hot waves of gas that sweep across the vast taiga forest, where fires burn for days and herds of reindeer burn to ashes. For a few days after the explosion, the sky over 9, 000 miles of Tunguska was shrouded in a ghosted orange color, a giant fire ball that stretched from the Lena river in the east to Ireland in the west and Tashkent and Bordeaux in the south. White nights have continued to appear in large areas of the northern hemisphere, and people as far away as Western Europe can read newspapers at night without lights. (4) Researchers at the Irkutsk earthquake station determined that the strange blast was the **alent of 10 to 15 million tons of TNT. A thousand times more powerful than the Hiroshima bomb that exploded more than thirty years later. (5) The Tunguska explosion site did not leave any direct evidence for study, and the cause of the explosion could only be inferred by analyzing the elements of the scene. Elemental analysis is certainly not as good as direct study of the debris, but it can also indirectly analyze the cause of the explosion from the side. Platinum group elements are generally regarded as indicative elements of extraterrestrial substances. If abnormalities of platinum group elements are found in explosive sediments, they are generally associated with extraterrestrial substances. The platinum-group elements in the crust of the earth are very, very low, and if you can find high levels in the crust, it’s easy to think about extraterrestrial material. (6) The platinum-group anomaly could be caused by a carbonaceous asteroid or the nucleus of a comet, but when it was combined with the isotope anomaly, it was almost impossible to find a carbonaceous asteroid. As we know, carbonaceous asteroids do not have such elements as hydrogen, but comets’ cometary vests and tails are made of ice and provide light elements such as carbon, hydrogen and oxygen. Scientists have also found anomalies in the explosive deposits of light elements such as carbon and oxygen, which makes comets more likely. The scientists’ findings provide an important piece of evidence for the comet impact theory and give us confidence in the comet’s conclusions. (7) The research of scientists on “Tunguska Explosion” is of great significance. Although there is an international consensus as to what caused it, anyone with a little knowledge of the matter can tell whether it was small celestial body hitting, and whether it was a comet or an asteroid is what they are studying. In fact, small celestial body impacts like this one have happened before, will happen again, and will always be there. There are now more than 150 of these impact craters on earth. The extinction of the dinosaurs 65 million years ago was caused by the worst meteorite impact we know of. (8) Within a few years after the explosion, scientists discovered three craters similar to lunar craters, which were about 90 to 200 meters in diameter, near tributaries of the Yenisei and Lena rivers. An area of primeval forest covering about 2000 square kilometers was knocked down by the shock wave. At least 300, 000 trees have died radially, and in some places the frozen soil has melted and turned into swamps. In subsequent expeditions, scientists also discovered that the soil in the blast area had been magnetized, that there had been abnormal radioactivity in tree rings from 1908 to 1909, and that some animals had genetic variations. (9) Since the second half of the 20th century, monitoring of the earth’s atmosphere has led humans to watch for airborne explosions of kiloton asteroids. According to the air force defense support program, such explosions occur about once a year. Ten million tons the size of Tunguska are very rare; Dr. Eugene Merle Shoemaker estimates that an asteroid of this size only happens once every 300 years or so. The 2013 Urals meteor event in Russia provided strong evidence for the asteroid explosion theory. A fireball brighter than the sun, a huge sonic boom, and a long trail of smoke in the sky all match the record of the Tunguska explosion, except that the asteroid that burned and exploded over Tunguska was significantly larger than that of 2013. (10) During the Tunguska explosion, trees directly below the center of the explosion were stripped of their branches and bark, while trees farther away were toppled by the blast wave, this phenomenon also observed during the nuclear test. 30 June each year as “International Day of the asteroid (Asterioid Day)”, in order to commemorate June 30, 1908, the earth’s worst small celestial body attacks “Siberian Tunguska event”, but also remind the world that don’t look down upon the impact of an asteroid, but until now, the event is still one of the 20th century’s greatest mysteries. https://archive.janatna.com/
