                            A telescope is an instrument used to observe distant objects by collecting and focusing light. Telescopes are used to study the sky and are an important tool in astronomy. They are also used to view distant stars, planets, galaxies, and other celestial bodies. Telescopes can also be used to observe the Earth and its environment, such as weather patterns and landscapes.  Telescopes come in a variety of shapes and sizes, depending on the type of observation they are designed to perform. The most common types of telescopes are refractors, reflectors, and catadioptric telescopes.
