radio telescope

(telescope that operates in the radio frequency range of EMR)

A radio telescope is an instrument designed to sense radio electromagnetic radiation at a distance, analogous to an "ordinary" telescope's ability to sense visible light at a distance. Many are reflector telescopes with a dish-shaped reflector directing radio waves to a small antenna that produces a corresponding oscillating electronic signal which can be recorded and analyzed. Radio astronomy, dealing with radio telescopes, radio sources, and methods and results of radio observations has become a major portion of astronomy. Example radio telescopes:
