List of radio telescopes - Wikipedia
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.
Radio telescope - Wikipedia
Radio telescopes are typically large parabolic ("dish") antennas similar to those employed in tracking and communicating with satellites and space probes. They may be used individually or linked together electronically in an array.
What are Radio Telescopes? - National Radio Astronomy …
We use radio telescopes to study naturally occurring radio light from stars, galaxies, black holes, and other astronomical objects. We can also use them to transmit and reflect radio light off of planetary bodies in our solar system.
Radio telescope | Images, Definition, & Facts | Britannica
Radio telescope, astronomical instrument consisting of a radio receiver and an antenna system that is used to detect radio-frequency radiation between wavelengths of about 10 meters (30 megahertz [MHz]) and 1 mm (300 gigahertz [GHz]) emitted by extraterrestrial sources.

2023年12月4日 · Radio telescopes come in all shapes and sizes, depending mainly on the radio wavelengths they are designed to receive. The most familiar sort is a curved dish that reflects radio waves to a...
Very Large Array – National Radio Astronomy Observatory
From the early 1960s at NRAO, astronomers knew they needed an array of radio dishes to complement the work of our giant, single-dish telescopes. An array is a group of several radio antennas observing together creating — in effect — a single telescope many miles across.
The Science of Radio Astronomy
What is Radio Astronomy? Astronomers around the world use radio telescopes to observe the naturally occurring radiowaves that come from stars, planets, galaxies, clouds of dust, and molecules of gas. Most of us are familiar with visible-light astronomy and what it …
