The Karl G. Jansky Very Large Array is a radio astronomy observatory on the Plains of San Agustin in central New Mexico, United States. It consists of 27 dish antennas, each 25 metres across, arranged in a Y shape along railway tracks so that they can be moved closer together or farther apart. By combining their signals, the array acts like a single giant telescope, producing sharp radio images of galaxies, black holes, star-forming regions and pulsars. It began operating at full strength around 1980 and was greatly upgraded in the 2000s, after which it was renamed in honour of Karl Jansky, the engineer who first detected radio waves from the Milky Way. It is operated by the National Radio Astronomy Observatory.
