The '''telescope''' is an [[optical]] instrument made with lenses and [[mirror]]s and shows magnified views of distant objects. Its [[invention]] is usually credited to [[Hans Lippershey]]. However, [[Galileo|Galileo Galilei]] made improvements. He was the first person to use telescope to look at objects in the [[sky]] and to write about what he discovered.

However, [[Galileo|Galileo Galilei]] later made significant improvements to the telescope. He was the first person to use telescope to look at objects in the [[sky]] and to write about what he discovered.
Galileo discovered the [[moon]]s that revolve around the [[planet]] [[Jupiter]]. These can seen by anyone with a pair of modern [[binocular]]s; they usually look like three or four [[star]]s that are close to Jupiter and all lined up in a straight line. This discovery was important, because at the time [[philosopher]]s and [[theologian]]s believed that everything in the [[universe]] revolved around the [[Earth]]. They even believed that this design reflected the will of [[God]]. Galileo's discoveries, and his insistence on publishing them, put him into conflict with the [[Catholic Church]] and even led to his being put under house arrest.
