VLA Radio Telescopes

The VLA consists of 27 separate dish antennas each measuring 82 feet in diameter. There are nine antennas on each of the three tracks that radiate out from the center of the array in a “Y” pattern. Each track is 21 kilometers long which allows for the array to grow and shrink in size (thereby adjusting resolution) depending on the requirements of the astronomers currently using the facility. The VLA has been used to study gamma ray bursts, pulsars, the sun and even to communicate with Voyager 2 as it passed Neptune in 1989.
