Very Large Array (VLA) in New Mexico. Now named the Karl G. Jansky VLA. It consists of 27 radio antennas in a Y-shaped configuration It acts as an interferometer with the data combined electronically, giving it the resolution of an antenna 36km in diameter. (Image credit: Jörg Dauerer)
The Very Large Array, one of the world's premier astronomical radio observatories, consists of 27 radio antennas in a Y-shaped configuration 50 miles west of Socorro, New Mexico. Each antenna is 82 feet (25 m) in diameter. The data from the antennas is combined electronically to give the resolution of an antenna 22 miles (36 km) across. Image courtesy of NRAO/AUI and NRAO
