Observatory salvaged In 1984, the Carnegie Institution for Science began the process of shutting down the observatories on Mount Wilson, opting to concentrate on newer sites in Chile. In 1986, the Mt. Wilson Institute was formed and plans to reopen the observatories were made so that by 2000 all the telescopes were back in operation. Construction began in 1996 for six 1-meter telescopes by the Center for High Angular Resolution Astronomy at Georgia State University. This was the largest optical interferometric array at the time. Ground was broken for the telescopes in 1999 and the facility became operational in 2001. See also Palomar Observatory Sierra Madre, California—at the base of Mt.
