In September 2011 in Buenos Aires was an explosion. This explosion, supposedly, was a ball of fire that fell from the sky. The result is a mysterious explosion one person was killed and six were seriously injured. Also collapsed the business office, two houses and several cars.

Occurred the incident of the night. According to eyewitnesses, shortly before the explosion to the ground from the sky flying ball of fire.

Recently similar mysterious balls of fire the inhabitants of the Earth see very often. So, a brilliant ball of fire at the end of September swept over the canadian province of Ontario. Eyewitnesses claimed that unusual ball was many times brighter than the moon. Sparkling mysterious ball watched and Northern Germany. Mysterious object crumbled to pieces right in the sky and silently fell to the ground for a few seconds.

Also known such an unusual phenomenon as "the February balls of fire" for the USA. A similar phenomenon was observed in 60-ies of the last century. However, this year this phenomenon puzzled experts, as fireballs this February penetrate into the atmosphere of unusual deeply and slowly. American astronomers puzzled not so much by the number of balls as the trajectory of their flight and their views. According to Professor Peter brown and his colleagues, these heavenly bodies burst into the Earth's atmosphere, with a speed of 15 km/sec, rapidly lose speed and cease to exist at a distance of about 50 kilometers from the earth's surface.

Thus, on 1 February this year the skies over Texas illuminated ball of fire, having arranged this unprecedented brightness of a luminescence and duration of the show. The ball has crossed the sky within just eight seconds. According to witnesses, at least slowing the ball exploded like fireworks or firecrackers and shattered into many pieces. He then repeatedly Pomerol and slowly burned. Brightness fireball gave not less than the Moon. His appearance was recorded by video cameras NASA in the state of new Mexico. By calculations of experts of management, space object width could be about 2 meters.

Balls of fire ask scientists riddles for many decades. Messages about monitoring set fire balls that fall from the sky, received from eyewitnesses from different parts of Texas. Similar phenomena were also seen in Kentucky. On the nature of origin of these balls in modern scientists there is no single point of view. Some researchers believe that the ball is the energy clot that forms in the atmosphere due to the effects of the solar wind. For others, the fireball is a form of ball lightning, which has not been studied.

But now there are new rather original hypothesis. In particular, Vasily Kropachev, an employee of the Siberian branch of the Russian Academy of Sciences, believes that balls of fire are the result of the strongest geomagnetic emissions arising from movements of tectonic plates. UFO researcher Dmitry Prytkov argues that this anomaly is related directly with the problem of extraterrestrial civilizations. Is it really something to do with UFOs?

About the existence of UFOs were arguing, and will always argue. Public opinion during the heated discussion was divided into two camps - some believe that extraterrestrials exist and their mysterious vehicle periodically in view of earthlings, others constantly refute any evidence of the existence of extraterrestrial civilizations. Supporters of the version about the existence of UFOs are much more active than the skeptics. Every day are multiplying eyewitness accounts that prove the existence of extraterrestrial civilizations.

One recent arguments for the existence of aliens is a case that happened in Kyrgyzstan. At night on January 13, Colbeck Ryspaev was returning with his family from the guests, he went on a high-mountainous highway Bishkek-Osh. About three nights hours, he witnessed a strange sight in the sky clearly seen two mysterious flying object that was very reminiscent of the traditional descriptions of UFOs.

At first, the family Ryspaeva hovering in the skies things took over the planes, but then Kolbiko appeared on this account vague doubts. He had a video camera, which he filmed the events. The result is a material lasting eight minutes, which was subsequently shown to the representatives of the local media. According to the staff of the newspaper "Vecherniy Bishkek", in the sky were clearly visible two unidentified glowing flying object, shaped much like the classic dish of the aliens.

Skeptics, of course, laugh, however, the weight and the evidence is growing steadily. Some ufologists trying to find an explanation for what purposes we arrive UFO. According to the most popular theory, extraterrestrial beings for hundreds of years arrive periodically on our planet with the purpose of control. Proponents of this theory claim that the residents of Bristol in 1270 seen above the city strange flying machine. They note also that one of the inhabitants of this device left him and the result is suffocated in the earth's atmosphere.

Residents of Nuremberg in 1561 noticed several of the objects with circular fire fell on the ground and then disappeared into the mist. Famous astronomer Edmund Halley in March 1716 noted the emergence of the brightest celestial body that lit the sky. Object radiated light so bright that if he were to read you. In the Persian Gulf in may 1879 the British naval ship was spotted two giant luminous object in the sky. They had a round shape and, rotating very slowly fell down almost to the sea surface. Mysterious objects were highly visible in half an hour.

However, despite all of this, is unlikely to change the balance of forces that support and refute the version of the existence of UFOs. To prove believers anything and so don't need, and skeptics even live alien may be called "Hollywood special effects"
