ALMA in its Compact Formation

ALMA in its Compact Formation

ALMA's antennas can be rearranged to simulate a single, big telescope or a very widespread array. In this smaller configuration, 12-meter antennas join the 7-meter antennas that are always in a compact formation. ALMA, when it is in its compact formation, sees the faintest objects in the radio Universe.
