The Very Large Array, one of the world's premier astronomical
radio observatories, consists of 27 radio antennas in a Y-shaped
configuration on the Plains of San Agustin fifty miles west of
Socorro, New Mexico. Each antenna is 25 meters (82 feet) in
diameter. The data from the antennas is combined electronically to
give the resolution of an antenna 36 km (22 miles) across, with the
equivalent sensitivity of a dish 130 meters (422 feet) in diameter.
