atacama large millimeter array discoveries

Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) have revealed an extremely distant and therefore very young galaxy that looks surprisingly like our Milky Way. The unparalleled power of ALMA made it possible to see this galaxy spinning at 170 miles (272 kilometers) per second, similar to our Milky Way. English: The Atacama Large Millimeter/sub-millimeter Array (ALMA) is an array of radio telescopes in the Atacama desert of northern Chile. Following mutual discussions over several years, the ALMA Project received a proposal from the National Astronomical Observatory of Japan (NAOJ) whereby Japan would provide the ACA (Atacama Compact Array) and three additional receiver bands for the large array, to form Enhanced ALMA. A report of the event and the preceding press conference is presented and the texts of the Atacama Large Millimeter/ submillimeter Array The result of an impressive international collaboration, ALMA is the largest astronomical project in existence. During Autumn 2009, the first three antennas were transported one-by-one to the Array Operations Site. One theory suggests that the faster accretion rate might be due to the complex magnetic field of the protoplanetary disk. Comparing data from VLA sky surveys made some two decades apart revealed that the black hole-powered “engines” at the cores of some distant galaxies have launched new, superfast jets of material during the interval between the surveys. On 28 July 2011, the first European antenna for ALMA arrived at the Chajnantor plateau, 5,000 meters above sea level, to join 15 antennas already in place from the other international partners. The Atacama Large Millimeter/Submillimeter Array (ALMA) is an international millimeter-wavelength radio telescope under construction in the Atacama Desert of northern Chile. ALMA is a premier telescope for studying the first stars and galaxies that emerged from the cosmic “dark ages” billions of years ago.

European/U.S. The Atacama Large Millimeter/Submillimeter Array (ALMA) is an international millimeter-wavelength radio telescope under construction in the Atacama Desert of northern Chile. At a cost of about USD 1.4 billion, ALMA is the most expensive ground-based telescope in operation in the world. New VLA images show how the crowded environment of a cluster of galaxies affects the individual galaxies, helping astronomers better understand some of the complex details of such an environment. At the end of 2009, a team of ALMA astronomers and engineers successfully linked three antennas at the 5,000-metre (16,000 ft) elevation observing site thus finishing the first stage of assembly and integration of the fledgling array. Using the now fully deployed Atacama Large Millimeter Array telescope in Chile, astronomers moved from observing comets to Titan. This was mainly for political reasons. “Most galaxies that we find early in the universe look like train wrecks because they underwent consistent and often ‘violent’ merging,” explained Neeleman. [18] Both transporters were delivered to the ALMA Operations Support Facility (OSF) in Chile on 15 February 2008. ALMA is an international partnership among Europe, the United States, Canada, Japan, South Korea, Taiwan, and Chile. The galaxy was initially discovered when ALMA examined the light from a more distant quasar (top left). The discovery contradicts theories that all galaxies in the early Universe were turbulent and unstable.
