The Discovery of Neptune Neptune was discovered in September 1845. It was discovered by means of mathematics before being seen through a telescope. It began in 1843 when John Adams‚ a young English astronomer and mathematician‚ began working to find thew location of the unknown planet. Adams predicted the planned would be about 1.6 billion kilometres farther from the sun then Uranus. That’s when he completed his work in September 1845. Also Urbain Leverriar‚ unknown to Adams‚ began working

He stated that the orbits of the planets are elliptical‚ that the planets revolve around the Sun at different speeds‚ and that there is a proportional relation between a planet’s orbital period and its distance to the Sun. Galileo was a backer of Copernican theory. He constructed an astronomical telescope in 1609 and made several discoveries‚ some

Factors that affect focal length- Factors that affect focal length are: • The curvature of then lens or mirror and in case of the lens. • The refractive index of the material the lens is made of. Telescope design- The refractor is what everyone recognises as a telescope; it has a lens‚ called the Objective lens at the front. In some designs‚ particularly smaller scopes‚ the air spaced doublet will be replaced by a compound lens with the two elements cemented together. Lens power-

about Galileo when he tried to convince the people of Rome "He had one more world to conquer: Rome-that is‚ the Church. In 1611‚ Galileo proposed to the grand duke ’s secretary of state an official visit to Rome in which he would demonstrate his telescopes and impress the Vatican with the importance of his astronomical discoveries"(19). The purpose of this visit was to convince the people of Rome and the Pope that‚ the sun is the center of universal not the Earth as the Greek philosopher

decided that the heliocentric theory could be mathematically supported. In 1632‚ Galileo Galilei published his proof to the heliocentric theory in Dialogue on the Two Great Systems if the World. Galileo was the first to use a telescope to look at stars and planets. Using the telescope‚ Galileo was able to prove that Earth rotated on its axis‚ and that Jupiter’s moons revolved around Jupiter‚ proving that not everything revolves around the earth. When Galileo published his ideas‚ it caused a major chaos

seeing the sky? Scientists look for black holes in space using telescopes that pick up x-ray‚ visible light‚ and radio waves. Using an x-ray telescope‚ a black hole can be detected by the discovery of a star’s gas being pulled into seemly nowhere. The gas being pulled from the star will form an accretion disk‚ which also allows for the indirect detection of a black hole. When we see an accretion disk or energy being

During his time in Padua he made a lot of scientific discoveries in both pure and applied science. One of his achievements was the improvement of the telescope. At that time telescopes were hard to made‚ rare to find and had bad quality. Galileo succeeded in making his own and improved telescope. His financial stats have raised by selling his telescope to merchants and the naval arsenal of Vennesse. It was sold to the naval arsenal so they can spot enemy ships hours before their arrival
