Telescopes are the primary instruments used to view distant objects in space. They work by collecting and magnifying light from celestial bodies, allowing astronomers to study stars, planets, galaxies, and other astronomical phenomena. Telescopes come in various types, including optical, radio, and infrared, each suited to different wavelengths of light. The invention of the telescope has significantly advanced our understanding of the universe, enabling discoveries such as the moons of Jupiter and the expansion of the universe. With ongoing advancements in technology, telescopes continue to evolve, enhancing our capability to explore the cosmos.
