Answers:
a radio telescope is an astronomical instrument that detects and collects radio waves from celestial objects, focusing on longer wavelengths. it uses a large parabolic dish or an array to collect radio waves and a receiver to convert them into electrical signals.
radio telescopes are used to study celestial objects, map cosmic structures, investigate active galactic nuclei, explore pulsars, detect hydrogen gas, search for extraterrestrial life, study cosmic microwave background, and monitor transient phenomena like gamma-ray bursts and supernovae. they play a crucial role in advancing our understanding of the universe, capturing emissions not observable with optical telescopes.
