The Very Large Array is a radio astronomy observatory consisting of 27 independent radio antennae, each of which has a dish diameter of 25 meters and weighs 230 tons. There are four commonly used configurations, designated A (the largest) through D (the tightest, when all the dishes are within 600 m of the center point). The observatory normally cycles through all the various possible configurations (including several hybrids) every 16 months.
