Telescope
A 'telescope' is an important tool for astronomy that gathers and focuses light. Some do this with curved mirrors, some with curved lenses, and some with both. Telescopes make far-away 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'.
