An aperture-synthesis radio telescope sited at an altitude of 2124 m on the Plains of San Agustin, west of Socorro, New Mexico, operated by the US National Radio Astronomy Observatory. It consists of 27 movable dishes of 25-m aperture, mounted along a Y-shaped railway track with arms 19, 21, and 21 km long. The telescopes can be arranged in four different configurations with maximum baselines of 1, 3.6, 10, and 36 km. It observes at wavelengths from 0.3 m to 6 mm. When opened in 1980, the telescope was known simply as the Very Large Array (VLA), but changed to its current name in 2012 in honour of the pioneer radio astronomer K. G. Jansky. Its headquarters are in Socorro, New Mexico.
