Atacama Large Millimeter Array

(ALMA)
(large radio telescope array in Chile)

The Atacama Large Millimeter Array (ALMA) is an interferometer array of radio telescopes on the Chajnantor Plateau in the Atacama Desert in Chile. It sits at an altitude of 5000 meters and consists of 66 12-meter and 7-meter movable dishes that observe millimeter and sub-millimeter wavelengths. It began operation in 2013 with 50 12-meter dishes, having been under construction since 2003. A later addition called the Atacama Compact Array (ACA) consists of sixteen additional 12-meter and 7-meter dishes with different specifications, including a wider field of view.
