Aerial view of ALMA

This aerial video shows a drones-eye view of ALMA, the international collaboration to create the world's largest ground-based facility for observations in the millimeter/submillimeter regime. Consisting of a giant array of fifty 12-m antennas, ALMA is the result of an international partnership of the European Southern Observatory (ESO), the U.S. National Science Foundation (NSF) and the National Institutes of Natural Sciences (NINS) of Japan in cooperation with the Republic of Chile.
