A night view of the Japanese antennas which form part of ALMA, the Atacama Large Millimeter/submillimeter Array — a huge new facility at 5000 metres above sea level on the Chajnantor Plateau, dedicated to studying the cool Universe. Captured in this UHD time-lapse.

ALMA construction and operations are led on behalf of Europe by ESO, on behalf of North America by the National Radio Astronomy Observatory (NRAO), which is managed by Associated Universities, Inc. (AUI) and on behalf of East Asia by theNational Astronomical Observatory of Japan (NAOJ). The Joint ALMA Observatory (JAO) provides the unified leadership and management of the construction, commissioning and operation of ALMA.
