One of the most unusual, mysterious and strange celestial bodies is considered to be Halley's comet.According to historical records, its history goes back now more than two thousand years.And that's just what recorded by ancient astronomers, who certainly did not know that they are dealing with the same subject over the centuries.Information available to the modern scientists, mankind owes to Edmund Halley, versatile scientist, who was able to summarize all references to comets and to compare them with their observations.In 1705 he published a work in which he describes his thoughts on the periodicity of the motion of comets.By the same conclusion he came to after being noticed in historical documents that at various times the Earth was approaching several comets moving along very similar trajectories.Based on the law of Newton's world attraction, Halley concluded that it is one and the same celestial body makes a complete revolution around the sun in about 75 - 76 years.He also suggested following the appearance of the object near the Earth, but the confirmation of his theory did not.After his death, the world's scientists have calculated the exact date of the appearance of the comet, and looking forward to her next visit.When the theory was confirmed, with the celestial body permanently fixed to the name of the one who first discovered it.
What is the Halley's Comet?Everyone else from astronomy course at the school know that comets are composed of ice core and a tail formed by vaporizing substances and tiny solid particles.In 1986, scientists were able to more fully understand what it consists of Halley's Comet.Photo, television images, observations from the European and Soviet probes revealed that the comet nucleus is half ice formed by frozen water, formaldehyde, carbon monoxide.In addition there is also a component of the ice dust, non-volatile light hydrocarbons.She begins her journey beyond the orbit of Neptune, and completes the turn, a little before they reach the orbit of Venus.Once every 76 years, Halley's comet approaches very close to the sun.Then the ice that makes up the core begins to evaporate, picks up with a speck of dust and rocky material and forms a delightful huge tail directed away from the sun.Large particles during flight gradually separated to form a meteor shower.Twice a year, in May and October, when our planet passes through the orbit of Halley's Comet, the inhabitants of Earth can watch this exciting spectacle.
Halley's Comet of interest not only to scientists, but also astrologers and magicians.Superstitious people associate her appearance with all sorts of disasters.Thus, according to myths and legends, thirteen and a half thousand years ago there was an apocalypse, which killed highly developed civilization, and humanity has returned to the wild life without writing, speech tools.According to the convictions of a number of astrologers and their estimated date of passage of the comet by the Earth, at a time it is visited by a celestial body in the vicinity of our planet.His theory, they argue providing "evidence", but rather an indication of the events that took place shortly before the occupant of this space: the earthquake in Lisbon in 1755 and Sicily in 1908, in Armenia, Mexico, Uzbekistan, in 1984 - 1988.
In addition, the mystics are inclined to believe that the significant adverse events in the life of humanity and the Earth occur at regular intervals, and they are connected with the place of the orbit, which at this moment is Halley's comet.2012 and the conflict between Japan and China they associate from 1936 year, the coming to power of the Nazis in Germany and the Spanish Civil War, in the years since the comet was at one point.They argue that the reason the Second World War is a mysterious comet passing close by militant Pluto.Similar events they predict in 2017 - 2021 years.
Whatever it was, but the inhabitants of the earth will soon be convinced of the correctness or falsity of these beliefs - is difficult to predict the years of very close, and she Halley's Comet visited us in 2061.
