1980: The Very Large Array (VLA) radio telescope network in New Mexico is dedicated. The VLA is arranged in a "Y" pattern, with nine antennas on each of the three arms. Each of the 27 antennae is a fully-steerable 82-foot diameter, parabolic dish, weighing about 230 tons. Information from all of its antennas is combined mathematically to produce resolving power equal to that of a single antenna as much as 22 miles in diameter. The VLA has made key observations of black holes and protoplanetary disks around young stars, discovered magnetic filaments and traced complex gas motions at the Milky Way's center.
