Última imagen disponible del conjunto central de antenas de ALMA, también llamado Array Operations Site (AOS), en el llano de Chajnantor, en vista que estamos bajo cierre total debido a la situación del coronavirus. The Chajnantor Observatory, a facility operated by the California Institute of Technology (Caltech) in collaboration with the University of Chile and the University of Concepción, is located at an elevation of 5080 meters (16700 feet) in the Andes mountains in northern Chile.The high, dry Chajnantor plateau is one of the best sites in the world for millimeter and submillimeter astronomy. Llano de Chajnantor Observatory er betegnelsen for en gruppe astronomiske observatorier i Atacamaørkenen i det nordlige Chile, beliggende i en højde af 4.800 m.o.h. Site Description This is because water vapour absorbs and attenuates submillimetre radiation. L'observatoire du Llano de Chajnantor est un observatoire astronomique, situé à une altitude de 5104 m, dans le désert d'Atacama, au Chili, 50 km à l'est du village de San Pedro de Atacama. Wiele międzynarodowych konsorcjów radioastronomicznych ulokowało tu swoje radioteleskopy – ACTpol, ALMA, APEX, ASTE, NANTEN2... i … It observed the microwave background, clusters of galaxies, and selected Galactic objects from 1999 to 2008. The zone has an exceptionally arid climate, inhospitable to humans. Rainfall at the ALMA site averages 100 mm (3.9 in) annually.The dry climate of Llano de Chajnantor is due to three factors: the rain shadows created by the Andes and the Chilean Coastal Range, the inversion created by the Humboldt Current off the coast of Chile, and dry air descending between the Hadley cell and the Ferrel cell, which forms the South Pacific High.While the site is generally viewed as being in the Atacama Desert, in terms of ecoregions it is in the Central Andean dry puna. Completion is expected in 2020. 28 October 2013 . Attached to the telescope is the POLARBEAR experiment, which is an array of bolometers cooled to less than 1 K (−458 °F). The first observatory instrument, the Cosmic Background Imager (CBI) is housed in a retractable dome to provide some protection from rain, snow, and wind. Stedet ligger i regionen Antofagasta omtrent 50 kilometer øst for byen San Pedro de Atacama.Det usædvanlig tørre ørkenklima i dette område er ugæstfrit for mennesker, men udgør et udmærket sted for submillimeter-astronomi. O Observatórios do Llano de Chajnantor é o nome de um grupo de observatórios astronômicos localizado a 5104 metros acima do nível médio do mar, no deserto de Atacama, Chile, a 50 quilômetros a leste de San Pedro de Atacama. It's one of the highest mountain roads of Chile. The observatory houses the world’s biggest and the most costly astronomical telescope project knows as the Atacama Large Millimeter Array. 0 references.

Identifiers. The NANTEN2 Observatory (NANTEN2) is 4.0 m (13.1 ft) millimeter-wavelength radio telescope operated by a consortium led by the University of Cologne. The Llano de Chajnantor in winter 1996, looking down from Cerro Toco. The project is led by the University of Chicago and was installed in 2009 in the facility that previously housed the CBI array. 65 likes. It was moved to a location on Cerro Toco near the ACT in 2011 and saw first light in January 2012. The measurements cover angular scales from a few arc minutes to several degrees. Telescopes In the first phase, two receivers have been constructed, one with 19 pixels at 44 GHz and another with 91 pixels at 90 GHz. That’s also good, because an observatory for millimeter waves needs to be at a very high altitude. Esta cámara de alta definición proporciona una vista interactiva y con un increíble nivel de detalle del telescopio, situado a 5.000 metros sobre […] The Atacama Cosmology Telescope (ACT) is 6.0 m (19.7 ft) Gregorian telescope designed to survey the sky at microwave wavelengths. The Atacama Desert is one of the driest places on Earth. Llano de Chajnantorin observatorio on rakenteilla oleva kansainvälinen observatorioalue Pohjois-Chilessä.Eurooppalaiset ovat mukana Chajnantorin rakentamisessa ja havaintotoiminnassa Euroopan eteläisen observatorion (ESO) kautta.. Chajnantorin tasanko sijaitsee noin 40 kilometriä itään San Pedro de Atacaman kaupungista. The desert climate in the area is unbearable for humans but is the best location for the millimeter and mid-infrared astronomy. When completed, it will contain as many as 66 antennas.
