The Karl G. Jansky Very Large Array (VLA), located on the Plains of San Agustin, New Mexico, is an exceedingly powerful scientific instrument which has transformed many areas of astronomy. Dedicated in 1980, the VLA consists of 27 antennas arranged in a “Y” pattern. To date, the VLA has been used by more astronomers producing more scientific papers than any other radio telescope in the world. The VLA exceeds all other radio astronomy facilities with its combination of sensitivity, flexibility, speed, and overall imaging quality. Among the observations at the VLA are: black holes and protoplanetary disks around young stars, the discovery of magnetic filaments and traced complex gas motions at the Milky Way’s center, probing the Universe’s cosmological parameters, and providing new knowledge about the physical mechanisms that produce radio emission.
