Blue Planet - it's not about the world, and of the distant planet of multi Uranus, the seventh from the sun.First Uranium mistaken for a star, so he was not available. Only in 1781, William Herschel discovered it as a planet. Uranus was a huge celestial body, full of surprises. It has 27 (!) Satellites, the largest of which Miranda, Ariel, Umbriel, Titania, Oberon, Cordelia, Ophelia, Bianca, Cressida, Desdemona, Juliet, Portia, Rosalind, Belinda, and in 1977 scientists discovered a system of 11 black rings.Uranium core is composed of stone and iron. The axis of rotation of the blue planet is tilted by 98 degrees - it revolves around the sun, "lying on its side", in the direction opposite to that in which all the planets revolve about. Year of the planet takes 84 Earth calendar.Diameter Uranus 4 times greater than the earth, and the atmosphere is composed of molecular hydrogen, helium, methane and small amounts of acetylene, hydrogen cyanide, carbon monoxide. The blue color of the planet - is the result of absorption of red light by atmospheric methane.Due to the location of the far planet receives solar energy in 140, and the light - 400 times smaller than our Earth. The temperature on the surface of Uranus - a gas giant planet - is very low and ranges from -208 to -212 degrees Celsius. But it is very hard aired: winds blowing parallel to the equator of the planet, are carried at the speed of 140-580 km / h.Again, in contrast to simple our Earth, Uranus has a magnetic pole 4: 2 major and 2 minor. They make the planet in a shell whose center does not coincide with the center of the planet. This is a unique case where the solar wind is so much distorts the magnetic field: the tail of the magnetosphere of Uranus stretches 10000000 km towards the orbit of Neptune!<span>Surprisingly, Uranus is not usually associated myths and legends. Only the last two centuries, the drafters of the horoscope into account its impact on human life.</span>
Thomas Edison's most famous <span>invention is probably the light-bulb; his
favourite </span>invention<span> was the phonograph. The phonograph, he said would </span><span>replace
shorthand typists and it would </span><span>be used to teach languages. He believed that a
phonograph and a clock would </span><span>actually say what the time was. He thought that
people would send phonographic </span><span>records instead of letters and that they
would record the </span><span>voices of their children and the </span><span>last worlds of the dying.
Edison also believed that people would listen to world-famous musicians
on phonographs in their own homes. People have </span><span><span>though</span> early forgotten Edison's invention, but it was actually an </span><span>early kind of records or cassete player.</span>
