What is a "telescope"?
A telescope is an optical instrument used to observe distant objects, such as stars, planets, and galaxies. It uses lenses or mirrors to gather and focus light, allowing the viewer to see objects far away in greater detail. Telescopes are commonly used in astronomy to study celestial bodies and in science to explore the universe. There are different types of telescopes, such as refracting telescopes, which use lenses, and reflecting telescopes, which use mirrors. Telescopes can be found in observatories or used for personal stargazing.
