The Green Bank Telescope, near the town of Green Bank, West Virginia, is the world's largest fully steerable radio telescope. The National Radio Astronomy Observatory (NRAO) and Associated Universities, Inc. operate it using funds from the National Science Foundation (NSF). It is surround by the 13,000 square miles of the only US national Radio Quiet Zone, established in 1958 by the FCC. The observatory contains many other notable telescopes, among them the 140 foot telescope that utilizes an equatorial mount uncommon for radio telescopes, three 85 foot telescopes forming an interferometer array, a 40 foot telescope used by school groups and organizations for small scale research, a fixed radio 'horn' built to observe Cygnus X-1, a bunk house to facilitate these guests, as well as a reproduction of the original antenna built by Karl Jansky while he worked for Bell Labs to detect the interference that was discovered to be previously unknown natural radio waves emitted by the universe.
