The Very Large Array (VLA) radio telescope network in N.M. was - TopicsExpress



          

The Very Large Array (VLA) radio telescope network in N.M. was dedicated on 10 October, 1980. Conceived in the 60s and built in the 70s the VLA is versatile and sensitive, with angular resolution comparable to that of the best ground-based optical telescopes. The VLA is an aperture synthesis interferometric instrument, designed to gain the resolving power of a very large antenna by utilising a number of smaller antennas. Information from all of its antennas is combined mathematically to produce resolving power equal to that of a single antenna as much as 36 km in diameter. 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-ft diameter parabolic dish, weighing approx. 230 tons.
