-The '''telescope''' is an [[optical]] instrument made with lenses and [[mirror]]s which shows magnified views of distant objects. The [[invention]] of the refracting telescope (or "spyglass") is usually credited to [[Hans Lippershey]]. When [[Galileo|Galileo Galilei]] encountered the spyglass, he made himself a much more powerful one, and was the first person in history to make detailed recorded observations of the objects in the nighttime sky.

-Galileo discovered lights that went back and forth around the [[planet]] [[Jupiter]], which we know know as the four largest [[moons of 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 believed that the geocentric 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.
-The simplest telescopes (e.g., the kind Galileo worked with) are built with two lenses in a tube (see [[Refraction]]).
-During the twentieth century, [[astronomer]]s built huge telescopes. Some of the most famous in the United States are:
-*the [[Lick Observatory]] on Mount Hamilton near San Jose, [[California]];
-*the [[Yerkes Observatory]] in the resort area on the shore of [[Lake Geneva]] in [[Wisconsin]];
-*the [[Mount Palomar Observatory]] near San Diego, [[California]];
-*the [[Keck Telescope]] on Mauna Kea in [[Hawaii]].
-*the [[Hubble Space Telescope]] in Earth orbit.
