Consisting of 27 radio telescopes linked together, the VLA is one of the most sensitive astronomical observation tools available to modern science. The VLA was built in the middle of the New Mexico desert to minimize outside radio interference, but the facility offers a full visitor's center and guided tours by the operational staff.

Each antenna is 25 meters (82 feet) in diameter. The data from the antennas is combined electronically to give the resolution of an antenna 36km (22 miles) across, with the sensitivity of a dish 130 meters (422 feet) in diameter.

The Visitor Center is open every day from 8:30 a.m. to dusk. A series of informative videos and exhibits introduce the science and technology behind the VLA, and a walking tour will take you to the base of one of the 230-ton antennas. From there you can climb up to the observation deck for a view of the array itself, as well as a look at a new prototype antenna.

Twice a year, a full tour is open to the public. Group tours can be scheduled throughout the year.
