The National Radio Astronomy Observatory (NRAO) has major facilities at three locations. The administrative headquarters is in Charlottesville, Virginia. The principal telescope sites are at Green Bank, West Virginia, and Socorro, New Mexico. At Green Bank and at the Very Large Array site, west of Socorro, NRAO maintains Visitor Centers for tourists. Also, at Kitt Peak, NRAO operates one of the ten antennas of the Very Long Baseline Array (VLBA), and this antenna can be seen from the walking tour starting at the Kitt Peak Visitor Center, operated by the National Optical Astronomy Observatories (NOAO, although a "sister" organization, is not affiliated with NRAO or AUI). Every year, thousands of visitors come to browse our visitor centers and see our radio telescopes. We hope you can come and enjoy these facilities.
