("Alma" means "soul" in Spanish and "learned" or "knowledgeable" in Arabic.) [1] ALMA is expected to provide insight on star birth during the early Stelliferous era and detailed imaging of local star and planet formation. 8 Cool Facts About the ALMA Telescope by Clara Moskowitz, SPACE.com Assistant Managing Editor ESO Photo Ambassador Babak Tafreshi snapped this remarkable image of the antennas of the Atacama Large Millimeter/submillimeter Array (ALMA), set against the splendour of the Milky Way. Start of Early Science Cycle 1. This video clip shows the distinguished guests, including the President of Chile, Sebastián Piñera, arriving at the ALMA Operations Support Facility (OSF), located at an altitude of 2900 meters in the Atacama Desert in Chile for the inauguration of the giant telescope. [42][43], In March 2020, ALMA was shut down due to the COVID-19 coronavirus crisis. Thirty-two 12-m antennas in the 12-m array. [3][11] (However, various space astronomy projects including Hubble Space Telescope, JWST, and several major planet probes have cost considerably more). [2] Costing about US$1.4 billion, it is the most expensive ground-based telescope in operation. A slideshow traces the potted history of the telescope, from Galileo to ALMA ALMA: New telescope can detect hidden gases that might hold the key to star and planetary formation. This close-up image reveals one such galaxy (orange), rich in carbon monoxide, showing it is primed for star formation. 01:32. Research led by Durham University and with observations made with the Atacama Large Millimeter Array (ALMA) telescope of the European Southern Observatory reveals that after the collision, one of the galaxies ejects 10,000 Suns-worth of gas every year. It also delayed the cycle 8 proposal submission deadline and suspended public visits to the site.[44]. As no known non-biological source of phosphine on Venus could produce phosphine in the concentrations detected, this indicated the presence of biological organisms in the atmosphere of Venus. ALMA images of two molecular clouds. ALMA, a telescope so powerful it can see into the past . ESO and NRAO worked together in technical, science, and management groups to define and organize a joint project between the two observatories with participation by Canada and Spain (the latter became a member of ESO later). Start of Early Science Cycle 0. European, North American & Japanese draft agreement, with Japan providing new extensions to ALMA. ALMA construction and operations are led on behalf of Europe by ESO, on behalf of North America by the National Radio Astronomy Observatory (NRAO), which is managed by Associated Universities, Inc (AUI) and on behalf of East Asia by the National Astronomical Observatory of Japan (NAOJ). Array configurations from approximately 150 m to 14 km, Faster and more flexible imaging instrument than the Very Large Array, Largest and most sensitive instrument in the world at millimeter and submillimeter wavelengths, Point source detection sensitivity 20 times better than the Very Large Array, Data reduction system will be CASA (Common Astronomy Software Applications) which is a new software package based on, This page was last edited on 29 December 2020, at 02:01. ALMA (Atacama Large Millimeter/submillimeter Array) is a radio telescope inaugurated in 2013. The 12-meter-diameter dish was manufactured by the European AEM Consortium and also marks the successful delivery of a total of 25 European antennas — the largest ESO contract so far. The most powerful radio telescope opens its eyes and shows us the universe as we've never seen. One theory suggests that the faster accretion rate might be due to the complex magnetic field of the protoplanetary disk. It is composed of 66 antennas, each several metres in diameter, and works in synergy as a single giant telescope thanks to the interferometry technique. The ACA works together with the main array in order to enhance the latter's wide-field imaging capability. ALMA is funded in Europe by the European Southern Observatory (ESO), in North America by the U.S. National Science Foundation (NSF) in cooperation with the National Research Council of Canada (NRC) and the National Science Council of Taiwan (NSC) and in East Asia by the National Institutes of Natural Sciences of Japan (NINS) in cooperation with the Academia Sinica (AS) in Taiwan. Share the excitement of the inauguration ceremony and contemplate the breathtaking images from ALMA itself and views of its unique environment in the Atacama Desert. [14] The first antenna was delivered in 2008, the last in 2011.[15]. [35], The Atacama Compact Array, ACA, is a subset of 16 closely separated antennas that will greatly improve ALMA's ability to study celestial objects with a large angular size, such as molecular clouds and nearby galaxies.
