A smaller array

This 360 degree panorama image shows the Chajnantor Plateau, located at an altitude of 5000 meters in the Chilean Andes, where the Atacama Large Millimeter/submillimeter Array (ALMA) is located. Shown here are the 12 smaller antennas, each with a diameter of 7 metres, that make up the ALMA Compact Array (ACA).��On the horizon, behind the antennas, the peaks of Cerro Chajnantor, Cerro Toco, and Juriques are visible.
