Born in Germany under the name Friedrich Wilhelm Herschel, it was only at the age of 30 that he discovered what his true passion. One night, while looking at the night sky with his sister Caroline, he discovered Uranus and several moons around other gas giants. During his lifetime, he compiled a catalog of 2,500 celestial objects still used in today's society. Early in his life, he mainly studied music with his sister. Her sister, Caroline, was the first woman to discover a comet, and the first woman to obtain a paid scientific position and receive honorary membership of the Royal Society. William Herschel will propose the theory of the evolution of stars. William Herschel's early years, William's father was an army musician. Following his father's profession, he played for the Hanoverian Guards. When the French captured Hanover in 1757, he fled to England where he earned his living copying music. He began improvising when he began teaching music, and eventually, he became a composer. In 1766 he was appointed organist of Beth Chapel. His curiosity for music led him to read Harmonics by Robert Smith. After finding Smith's book interesting, he read A Complete System of Opticks, which introduced him to building telescopes. Herschel told himself that he was not going to study the Sun and Moon like all the other astronomers were doing. Instead, he thought about trying to search for different celestial bodies. The problem was that he would need massive lenses for this job, far more than he could afford for a reasonable price, so he decided to sculpt them himself instead. They were ground from metal disks of copper, tin and antimony in various proportions. However, his attempts seemed useless, in the middle...... middle of paper...... it attracted many visitors. Even the princess and the dukes came to visit his precious telescope. While living in Slough, Herschel discovered four moons, two orbiting Saturn and two orbiting Uranus. Herschel's telescope also showed 75 million stars that were not previously visible. ConclusionWilliam Herschel is still known today for his telescopes sold around the world. He took something no one else would do and did what he was passionate about. Today he is credited with the discovery of Uranus and the discovery of 4 moons, two orbiting Saturn and two orbiting Uranus. With the help of his sister and brother, he was able to discover 2000 celestial bodies in the sky. Herschel was able to see 75 million stars that were not visible with any other telescope at the time. He was able to entertain princesses and dukes with his enormous telescope measuring 6 meters high..
