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 emitted by astronomical objects, just as optical teles...
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.
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 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...
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.
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 reveals about these objects.
Radio telescopes pick up signals from objects in the sky that aren’t made by humans. Some of these telescopes are big dishes, others look like fences or small vertical metal frameworks scattered across the landscape.
The Arecibo Telescope was a 305 m (1,000 ft) spherical reflector radio telescope built into a natural sinkhole at the Arecibo Observatory located near Arecibo, Puerto Rico.A cable-mount steerable receiver and several radar transmitters for emitting signals were mounted 150 m (492 ft) above the dish.Completed in November 1963, the Arecibo Telescope was the world's largest single-aperture ...
Radio astronomy reveals parts of the invisible sky. By detecting radio waves emitted by a wide range of astronomical objects and phenomena, radio telescopes provide a totally different view of our Universe.
Founded in 1956, the NRAO provides state-of-the-art radio telescope facilities for use by the international scientific community. NRAO telescopes are open to all astronomers regardless of institutional or national affiliation.
