Radio Telescope

A radio telescope is a specialized astronomical instrument used to detect radio waves from the universe. It operates in the radio frequency portion of the electromagnetic spectrum and is used to study celestial objects such as stars, galaxies, and other astronomical phenomena.

How Radio Telescopes Work

Radio telescopes consist of a large dish or array of dishes that collect and focus radio waves onto a receiver. The receiver then amplifies and processes the signals before they are analyzed by astronomers. Unlike optical telescopes, radio telescopes can operate during the day and night and are not affected by weather conditions, making them valuable tools for studying the universe.
