The observatory was established as the National Science Foundation's (NSF) National Radio Astronomy Observatory (NRAO) in 1956 and made its first observations in 1958.[2][3][4][5] It served as the NRAO's headquarters until 1966, after which the facility was known as the National Radio Astronomy Observatory, Green Bank.[3][6]
In October 2016, the observatory became an independent institution following a 2012 recommendation that the NSF fully divest itself from the facility by October 1, 2016.[4][7][8][9]
Green Bank Observatory subsequently retained partial NSF funding, established private contracts, and formed a partnership with West Virginia University.[10][4] It is operated by the nonprofit Associated Universities, Inc., under a cooperative agreement with the National Science Foundation.[10]
