Currently taking shape on the Chajnantor plain in the Chilean Andes, the Atacama Large Millimeter Array (ALMA) promises to revolutionize the search for molecules in the universe — and so much more. When completed in 2012, the observatory will house up to 64 antennae, each 39 feet (12m) in diameter and weighing 115 tons.
