WASHINGTON, D.C. - The Atacama Large Millimeter/submillimeter Array (ALMA) is an astronomical interferometer of radio telescopes in the Atacama Desert of northern Chile. The ALMA radio telescope is tuned to higher frequencies of radio waves, nearly as high as the infrared — type of light we feel as heat — radiated by most objects in the Universe. Called millimeter and submillimeter waves, this type of light is easily scattered away by water vapor in the air. The dry climate and 16,500-foot high altitude of the site in the Chilean Atacama Desert provides ALMA with the right conditions for detecting these faint signals from space.
