Time-Lapses of Night Sky Over ALMA Observatory on Chilean Plateau

The night sky is incredibly clear in these beautiful time-lapses by José Francisco Salgado of the ALMA observatory on the 5000 meter Chajnantor Plateau in Chile (see 1 and 2). The Atacama Large Millimeter/submillimeter Array (ALMA) is an international partnership to build “the world’s largest astronomical project” and will be tasked with studying the origins of the universe. It is projected to be fully operational in 2012 with a total of 66 radio antennas (four of the antennas are seen undergoing testing in the video).
