Hubble Telescope

Since ages, space has been a mysterious and interesting subject that we human beings only could stare at, until the development of the telescope, all astronomical observations were made with the eye. By using measuring instruments, astronomers documented the positions of the planets against the background of stars. In 1609, Galileo Galilei turned his telescope to the sky and expanded the whereabouts of science; planetary astronomy became a new and different science, moreover, the concerns about the motions of planets, surfaces of other worlds could now be studied as well. The telescope was one of the central instruments of what has been called the Scientific Revolution of the seventeenth century. Galileo Galilei constructed a twenty-powered instrument and turned it to outer space in 1609. With this instrument, he observed the Moon, discovered the four moons of Jupiter and resolved nebular patches into stars. As the years went by, and the well-known scientists Isaac Newton and Johannes Kepler were born, the development of the telescope took speed. The precision and shape of the telescopes varied from 5 to 7 feet in length to a 140-feet telescope, and from magnifying of four times to a magnifying of about 100 times.
