The telescope has also allowed us to look at nebulae or clouds of dust and gas in space. They have allowed us to see the surface of the moon and the weather patterns of other planets. The telescope has allowed us to observe planets and stars that are millions of miles away from our planet. Yet, the telescope did more than convince scientists that the sun was at the center of our Solar System. With the use of the telescope, Galileo realized that the sun was truly at the center. Nicolaus Copernicus argued that the Sun was the center of the Solar System. Telescopes have given us significant insight into the workings of the universe, allowing science to progress further. Did the Telescope Have a Major Impact on Science? The English form ‘telescope’ appeared in 1650. Galileo’s letters show that he used the term after Cesi. Telescope appeared in a letter from Frederico Cesi to Galileo in August 1611. The word ‘telescope’ comes from the Italian word telescopio, which appeared in the early 1600s. The smaller sizes also led to chromatic aberrations, meaning the telescope could not bring the colors of the object into focus or alignment. It was nearly impossible to see objects further away.Įarlier telescopes did not have a fixed place for the eye, meaning the images that appeared in the telescope would move out of sight or out of focus. Early telescopes were exceptionally small in size and had a limited viewing range. Galileo’s telescope, along with others built during the 1600s, had serious problems. Polished lenses and mirrors were placed inside the tubes to magnify images and reflect light.Ĭredit: Museo Galileo, Institute and Museum of the History of Science What Were the Major Problems with Early Telescopes? The tube could be made of tin, lead, cardboard, and wood held together by copper, cloth, or leather ties and/or glue. The first telescopes consisted of long tubes with one or several cylindrical sections. What did the First Telescope Look Like?Įarly telescopes looked similar. Galileo then made a telescope that could magnify objects by eight times. Thomas Harriot in England managed to build a telescope that could magnify objects six times. Over time, astronomers began to build telescopes that had more power and clearer images. Galileo’s telescope was the first to be used for space observation. Galileo picked up Lipperhey’s telescope and began to improve it. By the end of May in 1609, the telescope could easily be found and purchased in large cities like Paris. The telescope spread across Europe after Lipperhey. Other scientists and glass-makers came forward to claim that they had made similar devices Lipperhey was denied his patent because of the claims. A week later, Lipperhey applied to patent his new device. In September of 1608, Lipperhey took his telescope to Prince Maurice of Nassau. No other telescope makers had done this, and Lipperhey’s telescope was the beginning of the telescope’s evolution. When he reduced the amount of light and focused it, the images became clear but remained dim. Lipperhey put a mask on his telescope that only allowed a small amount of light to enter his telescope. It was at this time that Hans Lippershey, who made spectacles in the Netherlands, began experimenting with lenses. Due to their imperfections, they were not useful for astronomic observation.īy the end of the 1500s and early 1600s, lens makers improved their abilities to cut and polish glasses.

These lenses were not powerful, not polished, and not clear. In the 1400s, glasses were used widely across Europe. The telescope traces back to early makers of eyeglasses and lenses.

Let’s take a look at the telescope and its impact on scientific history. Historians and scientists today still argue about who invented the telescope. It is easy to point to Hans Lipperhey as the inventor of the telescope, but the history of its invention is chaotic and confusing. His model inspired other scientists to work on perfecting the telescope. Lipperhey was a German-Dutch glass maker, and he managed to reduce the amount of light in his telescope while focusing it. Many people believe that Galileo Galilei was the first astronomer to invent and build the telescope however, the first telescope was made by Hans Lippershey in the early 1600s.
