The Very Large Array (VLA or Karl G. Jansky Very Large Array) is an Interferometer Radio Telescope on the Plains of San Agustin, in New Mexico, named for Karl G. Jansky, physicist and Radio engineer. It is part of the National Radio Astronomy Observatory, its Elevation is 2124 m (6970 feet), and it has 27 independent 25-meter antennas. It operates at Wavelengths 0.6 to 410 cm (50 GHz-73MHz) and using Interferometry, resolves to an angles as small as .05 arcsecond.
It was built in 1973-1980 under the name Very Large Array (VLA) and was renamed (attaching Jansky's name) with 2001-2012 upgrade replacing all the electronics.
