His musical genius made him a success in the UK. 1766, he has become the holy city of Bath, famous organist and music teacher. Financial security provided for the Herschel condition to meet their strong thirst for knowledge. He taught himself Latin and Italian. Theory of music that he studied under the mathematics, which in turn access to the optics. To study the optical made him read a book about Newton, and suddenly he had to witness a strong desire to see a variety of objects. He can not afford a telescope, it was decided to grind the lens yourself, personally manufacturing Sky equipment. He tried 200 times, only create a more satisfied with the telescope. He returned to Hanover in 1772, spent a long time to find his sister Cahe Herschel, took her to England. Facts have proved that this is very good news, Cahe Herschel as obsessed with his own grinding lenses, and later became an outstanding astronomer. If if is not the full support of his sister, Herschel I can not get that much success. In 1774, he had the best time to create a reflecting telescope, reflector telescope, and for the first time that the performance of more than a refracting telescope was widely used. He made him even more powerful telescope, he described the case of the lunar mountains and the discussion of variable stars, the change of sunspot activity may affect agriculture and the earth point of view, a sensation throughout the scientific community. In 1781, when Herschel very good with his telescope frame from another star a star turn, he saw an object is not just a blip, but showed a small round face. Naturally, he thought he discovered a new comet. However, further observations showed that the problem is not that simple. First, the edge of the small round face and clear like the edge of the comet, as always vague, and secondly, in the calculation of its orbit and found almost a circle, not very long, as the comet. Herschel is a surprise to the conclusion: He found a new planet is. This discovery will be known at the time of the solar system in one fell swoop Extension range doubled. This is the first ever people find a new planet. III was King of England know that rule, Herschel will try to Fengyun star named "George of the Star." In Lalande's proposal, some astronomers advocate called it "Herschel Star", will honor attributed to the discoverer. Finally, the views of the majority Greek mythology or inherit the tradition of naming planets, to the gods Eula Corners (uranus) named after it. News discovered Uranus caused a great sensation. Astronomers once thought that after the Newton will not have anything new to discover. Herschel's discovery is like a breath of fresh air, it tells people there is the unknown. 1781 Herschel was elected member of the Royal Society, and won the Copley Medal. Hanover, King George has blood. His hometown for his brilliant achievements made are pleased to appoint Herschel as his private astronomer, the annual salary of 300 guineas coins. After the discovery of Uranus, Herschel did not completely ignore the solar system. He re-telescope observations with better Uranus, discovered in 1787 its two satellites, "Titania" and "Olympic White Dragon" (ie, Titania and Oberon), who also reported that he found the other 4 satellites of Uranus's satellites, but later proved to be wrong. Herschel is not long before they built a new telescope, it is up to 40 feet, there is a 48-inch reflector. George III for the construction of the telescope donated 4,000 pounds. Put into use in the telescope the first night, Herschel point it to Saturn, and immediately found two new ---- Titan Enceladus and Mimas, with Huygens, and found a card Sydney found that the four, making a total of Fengyun ringed planet has seven moons. 1816, Herschel was awarded the title. He has 81 years in 1819, also conducted a final observation. He lived to 84 years, Uranus around the sun exactly equal to the orbital period. |
