Stars and Telescopes

Telescopes are considered to be an instrument that makes distant objects to appear closer, (Northwestern, 2012). These instruments have assisted scientists and astronomers in their studies of the universe. With the use of a telescope the studies have changed and become easier to study. This paper will provide information on how the telescope has changed the views of the universe, designs of telescopes, ground-based telescopes, strengths and weaknesses of the location of the telescope, different frequencies of light, and the wavelengths of a telescope. Studies of the universe occurred before the telescope was invented, but was much harder. Today, the telescope has assisted in the many discoveries of the universe. Without a telescope, many of these discoveries may have not been possible. The telescope has become a main instrument and icon in the world of science. The telescope has opened up opportunities to scientists than in the past, improving the studies and discoveries. Telescopes have changed many views of the universe. The first view that was changed is that the Earth is not the center of the universe. The telescope allows viewing of mountains and craters of the moon, asteroids, new planets, etc. (NASA, 2010). The telescope has also allowed scientists to properly measure the speed of light and to understand the light of stars and Sun, (NASA, 2010). While telescopes have opened up a new world of opportunities, there are many designs that can be chosen from. There are three main designs of telescopes; refractors, reflectors, and a catadioptric. The refracting telescope is one of the most common telescopes. The refractor telescope captures an image through the lens and bends it. After it is bent, it is sent to the focal point and modified by the lens and viewed through the eye piece, (Telescopes, 2013). The refracting telescope is among one the most popular telescopes because the strengths of the telescope. This type of telescope is long lasting, useful in
