introduction of telescope explain 200 words​

Answer 1

A telescope is an important tool for astronomy that gathers light and directs it to a single point. Some do this with curved mirrors, some with curved lenses, and some with both. Telescopes make distant things look bigger, brighter and closer. Galileo was the first person to use a telescope for astronomy, but he did not invent them. The first telescope was invented in the Netherlands in 1608. Some telescopes, not mainly used for astronomy, are binoculars, camera lenses, or spyglasses.

Most big telescopes for astronomy are made for looking very carefully at things that are already known. Newtonian telescopes are an example. A few are made to search for things, such as unknown asteroids. They are sometimes called "astrographs".
