ABOVE: The Atacama Large Millimeter/submillimeter Array at its 16,500 ft elevation site in northern Chile. Still under construction, ALMA is the most powerful telescope of its kind in the world. At the time of this photo, 19 radio telescopes were in the array. Upon completion in 2013, 66 radio telescopes will fan over a nearly 100 square mile area.

ABOVE: In this set of video clips, we establish ALMA's location on the Chajnantor Plain of northern Chile then zoom in to see its many styles of telescopes working together to observe the skies as one.

ABOVE: The Atacama Large Millimeter/submillimeter Array can be rearranged to suit different astronomy observing needs. During their relocations, the 115-ton telescopes are kept powered on the back of the gentle monster trucks, ALMA Transporters.
