In this video you can see ALMA at its 16,500 ft elevation site in northern Chile. Despite the fact that it is still under construction, ALMA is the most powerful telescope of its kind in the world. For the start of Early Science, around one third of ALMA's eventual 66 radio telescopes will make up the growing array. Upon completion in 2013, 66 radio telescopes will fan over a nearly 100 square mile area.
