ALMA moves!

ALMA is one of the largest ground-based astronomy projects of the next decade. It will be comprised of some sixty-four 12-meter, submillimeter-quality antennas at the high-altitude (5000 m) Llano de Chajnantor, possibly the world's best site for millimeter astronomy, close to San Pedro de Atacama in northern Chile.

This video clip shows a new impressive animation of the Atacama Large Millimeter Array (ALMA) during which the sixty-four 12-m antennas turn in different directions. To begin with, the "camera" is located near the base of one of the antenna units, with a view through the "antenna forest". It moves along several of the units, and then in a sweeping upward curve to a final view of the entire array as it may look like in its compact configuration.
