This is a list of radio telescopes – over one hundred – that are or have been used for radio astronomy. The list includes both single dishes and interferometric arrays. The list is sorted by region, then by name; unnamed telescopes are in reverse size order at the end of the list. The first radio telescope was invented in 1932, when Karl ...

A radio telescope is a specialized antenna and radio receiver used to detect radio waves from astronomical radio sources in the sky. [ 1 ] [ 2 ] [ 3 ] Radio telescopes are the main observing instrument used in radio astronomy , which studies the radio frequency portion of the electromagnetic spectrum , just as optical telescopes are used to ...
