    The largest astronomical project in existence is getting under way in the high plains of northern Chile. The Atacama Large Millimeter Array, or ALMA, will be comprised of 66 giant 40-foot and 23-foot antennas, spread over 11.5 miles, operating as a single, giant radio telescope. ALMA will help astronomers answer questions about our cosmic origins and will observe some of coldest and most distant objects in the cosmos.
