A telescope is an optical instrument that makes far objects appear larger by using lenses or curved mirrors and lenses. We can study the sky and the stars through a telescope. The first known practical telescopes were telescopes invented in the Netherlands at the beginning of the 17th century; glass lenses were used in them. They are used for looking at things that are too far and studying them carefully. Large telescopes are used by astronomers. Telescopes are the main instruments for the study of the night sky. Home telescopes are used to look at some astronomical events that may take place in the sky. In the 20th century, many new types of telescopes were invented, including radio telescopes. The Hubble Space Telescope is a space telescope which started working in space in 1990.
