The Atacama Large Millimeter Array (ALMA) is an array of separate telescopes in the Atacama desert of northern Chile.

Consisting of 66 12-metre (39 ft) and 7-metre (23 ft) diameter radio telescopes observing at millimeter and submillimeter wavelengths, ALMA is expected to provide insight on star birth during the early universe and detailed imaging of local star and planet formation.

ALMA is an international partnership among Europe, the United States, Canada, Japan, South Korea, Taiwan, and Chile.
