Green Bank, West Virginia, USA: the only US national Radio Quiet Zone (by FCC 1958-now). Green Bank Telescope is world's largest fully steerable radio telescope.

Green Bank, West Virginia, is surrounded by 13,000 square miles of the only US national Radio Quiet Zone (established in 1958 by the FCC). The Green Bank Telescope 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). 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.
