The Very Large Array, often referred to as simply the VLA, is a collection of 27 radio dish antennas located near Socorro, New Mexico. Each antenna is an 82-foot diameter radio dish and they are mounted on rails in a Y-configuration, allowing the distance between the antennas to be changed. The antennas do not operate individually, but rather work together in a network using the principle of interferometry--in effect creating a single telescope up to 22.6 miles across, dramatically increasing its resolution. |
