The Atacama Large Millimeter/submillimeter Array (ALMA) is the most complex astronomical observatory ever built on Earth. The most notorious is the Atacama Large Millimeter Array (ALMA), an astronomical interferometer of 66 radio telescopes in the Atacama Desert (on the Chilean side). The Atacama Large Millimeter/submillimeter Array (ALMA) is an astronomical interferometer of 66 radio telescopes in the Atacama Desert of northern Chile, which observe electromagnetic radiation at millimeter and submillimeter wavelengths. The Atacama Compact Arrayo, part of the Atacama Large Millimeter/submillimeter Array, is comprised of 16 antennas that enhance ALMA’s ability to study celestial objects with large angular sizes such as molecular clouds and nearby galaxies. The high sensitivity is mainly achieved through the large numbers of antenna dishes that will make up the array. ALMA will be situated on a high-altitude site at 5000 m elevation which provides excellent atmospheric transmission over the instrument wavelength range of 0.3 to 3 mm. Both facilities observed Venus at a wavelength of about 1 millimeter, much longer than the human eye can see — only telescopes at high altitude can detect it … March 13, 2013. The Atacama Large Millimeter Array (ALMA) is a billion-dollar, international telescope project under construction in northern Chile on a 5-km elevation site at Chajnantor. First antenna movement with a transporter. [16] The solution chosen is to use two custom 28-wheel self-loading heavy haulers. The initial ALMA array is composed of 66 high-precision antennas, and operates at wavelengths of 3.6 to 0.32 millimeters (31 to 1000 GHz). “We think the Wolfe Disk has grown primarily through the steady accretion of cold gas,” said J. Xavier Prochaska, of the University of California, Santa Cruz and coauthor of the paper. Activates for operating the ARC have also divided into the three main regions involved (Europe, North America and East Asia). NRAO also provides both formal and informal programs in education and public outreach for teachers, students, the general public, and the media. Although ALMA did not observe the entire galaxy merger, the result is the best submillimeter-wavelength image ever made of the Antennae Galaxies, showing the clouds of dense cold gas from which new stars form, which cannot be seen using visible light. News and Public Information Manager It’s as easy as looking up. The discovery contradicts theories that all galaxies in the early Universe were turbulent and unstable. [3][11] (However, various space astronomy projects including Hubble Space Telescope, JWST, and several major planet probes have cost considerably more). The most notorious is the Atacama Large Millimeter Array (ALMA), an astronomical interferometer of 66 radio telescopes in the Atacama Desert (on the Chilean side). [21] In October 2012, 43 of the 66 antennas had been set up. The Joint ALMA Observatory (JAO) provides the unified leadership and management of the construction, commissioning and operation of ALMA. The discovery of the Wolfe Disk provides a challenge for many galaxy formation simulations, which predict that massive galaxies at this point in the evolution of the cosmos grew through many mergers of smaller galaxies and hot clumps of gas. A series of resolutions and agreements led to the choice of "Atacama Large Millimeter Array", or ALMA, as the name of the new array in March 1999 and the signing of the ALMA Agreement on 25 February 2003, between the North American and European parties. operated under cooperative agreement by Associated Universities, Inc. During an early stage of the planning of ALMA, it was decided to employ ALMA antennas designed and constructed by known companies in North America, Europe, and Japan, rather than using one single design. inijman@nrao.edu, This research was presented in a paper titled “A Cold, Massive, Rotating Disk 1.5 Billion Years after the Atacama Large Millimeter/submillimeter Array (prescurtat ALMA, care înseamnă suflet în spaniolă) este un radiotelescop interferometric situat la altitudinea de 5100 m, în deșertul Atacama din Chile.
