'The Atacama Large Millimeter/submillimeter Array, under construction. ALMA will be initially composed of 66 antennas, consisting a main array of fifty 12-meter antennas that can be spread over distances from 150 metres to 16 kilometers. In addition to the main array, ALMA will also have a compact array, composed of four 12-meter antennas plus twelve 7-meter antennas. By using the technique of interferometry, ALMA will work as a single giant telescope, enabling astronomers to observe the cold universe with unprecedented sensitivity and resolution.
