Astronomers use telescopes to study space by collecting and analyzing electromagnetic radiation from celestial objects. Telescopes can be optical, radio, or other types, each designed to detect specific wavelengths of radiation. Optical telescopes use lenses or mirrors to focus visible light, while radio telescopes capture radio waves. Telescopes can also be placed in space to avoid atmospheric interference. Astronomers analyze the data collected to learn about the properties, composition, and behavior of celestial objects.
