EMBRACE (telescope)
EMBRACE (Electronic MultiBeam Radio Astronomy ConcEpt) is a prototype radio telescope for phase two of the Square Kilometre Array (SKA) project. It's the first dense phased array for radioastronomy in the GHz frequency range (initially planned for covering the 0.5-1.5 GHz, mid-frequency band of SKA). It is composed of two sites, one at the Nançay radio telescope station in France, and one near the Westerbork Synthesis Radio Telescope The Westerbork Synthesis Radio Telescope (WSRT) is an aperture synthesis interferometer built on the site of the former World War II Nazi detention and transit camp Westerbork, north of the village of Westerbork, Midden-Drenthe, in the northea ... antennas in Netherlands.

Radio Telescope
A radio telescope is a specialized antenna and radio receiver used to detect radio waves from astronomical radio sources in the sky. 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 telescopes are the main observing instrument used in traditional optical astronomy which studies the light wave portion of the spectrum coming from astronomical objects. Unlike optical telescopes, radio telescopes can be used in the daytime as well as at night. Since astronomical radio sources such as planets, stars, nebulas and galaxies are very far away, the radio waves coming from them are extremely weak, so radio telescopes require very large antennas to collect enough radio energy to study them, and extremely sensitive receiving equipment. Radio telescopes are typically large parabolic ("dish") antennas similar to those employed in tracking an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Square Kilometre Array
The Square Kilometre Array (SKA) is an intergovernmental international radio telescope project being built in Australia (low-frequency) and South Africa (mid-frequency). The combining infrastructure, the Square Kilometre Array Observatory (SKAO), and headquarters, are located at the Jodrell Bank Observatory in the United Kingdom. The SKA cores are being built in the southern hemisphere, where the view of the Milky Way galaxy is the best and radio interference at its least. Conceived in the 1990s, and further developed and designed by the late-2010s, when completed a total collecting area of approximately one square kilometre. It will operate over a wide range of frequencies and its size will make it 50 times more sensitive than any other radio instrument. If built as planned, it should be able to survey the sky more than ten thousand times faster than before. With receiving stations extending out to a distance of at least from a concentrated central core, it will exploit r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nançay Radio Telescope
Nançay () is a commune in the Cher department in central France. Geography The village is located south of the Sologne and northeast of Vierzon. The Rère flows southwest through the middle of the commune. History Its name comes from Nanciacos and first appeared in 1010 (Acts of the Abbot Engilbert). The territory belonged successively to the County of Sancerre and the area of La Chatre. Joan of Arc stayed there, leaving her name to the ''spring maiden.'' Its castle dates from the fifteenth century, and was rebuilt during the Renaissance. Population Sights *The Nançay Radio Observatory, north of the town. The site was chosen in 1953 by the École Normale Supérieure because of its size, its relative proximity to Paris and the lack of industrial base that can generate noise. Inaugurated by Charles de Gaulle in 1965. The by diameter decametric network (144 branches in 10 000 m²). *ThPôle des Étoilesoffers tours of the Radioastronomy facility, planetarium shows and self-g ...

Westerbork Synthesis Radio Telescope
The Westerbork Synthesis Radio Telescope (WSRT) is an aperture synthesis interferometer built on the site of the former World War II Nazi detention and transit camp Westerbork, north of the village of Westerbork, Midden-Drenthe, in the northeastern Netherlands. Overview The WRST comprises fourteen 25-metre radio telescopes deployed in a linear array arranged on a East-West line, of which 10 are in a fixed equidistant position, 2 are nearby on a 300 m rail track, and 2 are located a kilometer eastwards on another 200 m rail track. It has a similar arrangement to other radio telescopes such as the One-Mile Telescope, Australia Telescope Compact Array and the Ryle Telescope. Its Equatorial mount is what sets it apart from most other radio telescopes, most of which have an Altazimuth mount. This makes it specifically useful for specific types of science, like polarized emission research as the detectors maintain a constant orientation on the sky during an observation. Ten of the t ...
