a device used in radio astronomy for detecting and recording radio waves coming from stars and other celestial objects
an astronomical instrument consisting of a radio receiver and an antenna system that is used to detect radio-frequency radiation emitted by extraterrestrial sources
a precise pointing device
a radio receiver-antenna combination used for observation in radio astronomy.
A telescope designed to make observations in radio wavelengths.
A large and precise instrument that basically has three important parts: an antenna to pick up the extraterrestrial radiation, a receiving system to amplify and measure the signal, and a computer.
An antenna (or set of antennas) designed, in conjuction with receivers, to detect and record the radio wavelength emissions of astrophysical phemomena. These instruments are typically much more sensitive than the common radio, but do have many similar features. Often a radio telescope looks superficially like a satellite dish (perhaps a large one), or a set of such dishes, but other radio telescopes do not. More.
a telescope designed to detect radio waves coming from space
An antenna or set of antennas that is used to detect radio radiation from space.
Also called an antenna (see above), this is a device for collecting the radio waves that are put out by objects in space (such as individual stars, whole galaxies, supernova remnants, etc.). Most radio telescopes look like satellite communication dishes. You don't look through a radio telescope; instead, the radio waves are collected, turned into electrical signals and then processed by computers. The end result is usually a picture: like a photograph, but made with radio waves instead of light.
A type of telescope that gathers and focuses radio wavelength light. Radio telescopes are huge dish-shaped antennae. Because of the long wavelengths of radio radiation, it is possible, and quite useful, to use many radio telescopes in different locations together in arrays. By combining telescopes in this way, astronomers are able to study celestial objects with much higher resolution than they could with a single antenna. An example of a radio telescope array is the Very Large Array, or VLA, which lies 80 kilometers west of Soccoro, New Mexico. VLA consists of 27 radio telescopes that are arranged in a "Y" pattern; each antenna has a parabolic dish shape and measures 25 meters across. Radio telescopes can probe the Galaxy and the universe where optical telescopes cannot. Astronomers have used radio telescopes to map the hydrogen content of our galaxy and to discover structures and processes in other galaxies that are invisible to optical telescopes.
A device capable of detecting radio waves from the cosmos.
A telescope shaped like a satellite dish which allows astronomers to collect radio waves from space.
A radio telescope is a metal dish that gathers radio waves from space. One example is the Very Large Array (VLA) in New Mexico.
A radio telescope is a form of directional radio antenna most often used in radio astronomy and in tracking and collecting data from satellites and space probes (see Deep Space Network), and are also used in the SETI project. In their astronomical role they differ from optical telescopes in that they operate in the radio frequency portion of the electromagnetic spectrum where they can detect and collect data on radio sources. Radio telescopes are typically large parabolic ("dish") antenna used singularly or in an array.
