The device commonly used to see objects that are far away is a telescope. Telescopes gather and magnify light to provide a clearer view of distant celestial bodies like stars, planets, and galaxies. There are different types of telescopes, including refracting telescopes, which use lenses, and reflecting telescopes, which use mirrors. Astronomers utilize telescopes for research and observation purposes, enabling discoveries about the universe's nature and structure. Notable telescopes, such as the Hubble Space Telescope, have vastly expanded our understanding of outer space and deepened our appreciation for its wonders.
