The Atacama large Millimeter/Sub-millimeter Array, or ALMA, is a vast array of radio telescopes and the most powerful observatory of its kind. ALMA is stationed in the Atacama Desert of Chile, which is one of the world's best sites for observational astronomy due to the high altitude, nearly non-existent cloud cover, dry air, and lack of light pollution and radio interference due to the low local population density. ALMA peers into previously hidden regions of space with unprecedented sharpness and sensitivity.
