The History of Telescopes

Galileo was the second person to make a telescope; his telescope could magnify objects three times their size. Soon he made another telescope that could magnify objects twenty times their size. With this telescope he could see the moon, and learned new information about other planets.

Johannes Hevelius made a refracting telescope that was 150 feet long. He had previously made other refracting telescopes before this one; one being 12 feet long. Then made ones that were 60 and 70 feet long. He was not satisfied untill he hade made one that was 150 feet long telescope. Since it was hard to work with, it was rarely used

Hans Lippershey was the first person to think of the telescope. He was a German-Dutch lensmaker, and he said that he wanted to build a instrument for seeing things far away. He made an instrument for that, which lead to Galileo's telescope.

Sir William Herschel discovered Uranus in 1781, then in 1798 he made a 40-foot telescope with the help of King George III. Although, because of the size, it was a little hard to work with. 1841 was the last time it was used.

Mr. Wilson made a 100-inch telescope that saw the first light in 1917 at Mount Wilson Observatory in Pasadena, California. In 1920 Edwin Hubble made discoveries beyond the Milky Way. Mt. Wilson's telescope was the largest telescope from 1917 to 1949.

The twin-mirrored Large Binocular Telescope saw light in Arizona in 2005. It was able to see things ten times better than the Hubble Space Telescope. It was also in the new generation of giant telescopes; these telscopes would help us learn more about the universe and shed light on things we do not know about previously.
