Summary

This documentary explores the Atacama Large Millimeter Array (ALMA), the largest ground-based observatory, located on the Chajnantor Plateau in Chile’s Atacama Desert. It details the engineering challenges of assembling 66 radio antennas at 5,000 meters altitude, where the thin, dry atmosphere is crucial for observing millimeter and submillimeter wavelengths. The film explains how ALMA’s interferometric technique links antennas to act as a single giant telescope, achieving high resolution. Scientists discuss key research areas: observing planet formation around the star Fomalhaut, studying molecular gas and star birth in obscured regions, and probing the supermassive black hole at the center of the Milky Way. The documentary also covers the logistics of operating the facility, including water supply and the use of oxygen by staff. It highlights ALMA’s ability to see through dust clouds, revealing the early universe and the formation of stars and galaxies. The narrative emphasizes ALMA’s role in answering fundamental questions about cosmic origins and the potential for habitable planets.
