Why is the history of telescopes an interesting one?

History of telescope has an interesting story. In 1609, the Italian scientist Galileo first peered through his small homemade telescopes have increased our knowledge of the heavens by leaps and bounds.

The first telescopes used to peer into space were refracting telescopes. This means that you would look straight through the telescope from one lens to the other, to the image you wear looking at. However, the lenses used in these telescopes were not the best, and the images were blurry. It was soon discovered that if the telescope lenses were further apart, they would show a telescopes began to get really long.

In the 1680s, Isaac Newton designed a successful reflecting telescope. This type of telescope had a mirror inside that would reflect the image to a focus point. Newton found that this made the images of space much clearer to the viewer. Since that time, humans have raced to build bigger and better telescopes.

Nowadays, there are many different types of telescopes. There are radio telescopes, X-ray telescopes, gamma ray telescopes and ultraviolet telescopes.
