ALMA is the Atacama Large Millimeter/submillimeter Array located in Northern Chile. Situated on the thin, dry air of the Atacama desert, 5000 meters above sea level, this is the ideal place to set up the world's largest array of Radio Telescopes. Although located in Chile it is a worldwide collaboration with three organisations leading the way - European Southern Observatory (ESO) (Europe), U.S. National Science Foundation (NSF) (USA) and National Institutes of Natural Sciences (NINS) (Japan).
