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.
