How humanity built the world's most powerful telescope in the high Atacama Desert

This 16-minute documentary chronicles the development of the Atacama Large Millimeter/submillimeter Array. It details the international collaboration required to construct a massive observatory in the harsh, remote environment of the Chilean Andes to study the coldest, most distant reaches of space.

The ALMA project represents a unified effort between Europe, North America, and East Asia to create a telescope capable of observing millimetre and submillimetre wavelengths. The film documents the logistical and technical hurdles of installing 66 antennas on the Chajnantor Plateau, situated 5000 metres above sea level in Chile's Atacama Desert.

Beyond the engineering feats, the video explores the scientific potential of the array. It highlights early research findings achieved even before the facility reached full completion, demonstrating the telescope's capacity to unlock new insights into cosmic origins.
