A radio observatory at Westford, Massachusetts, founded in 1960. Its main instrument is a 36.6-m dish, housed within a radome (protective dome), opened in 1964 and originally used for radar observations of planets but now mostly used for radio astronomy. It is operated by the Northeast Radio Observatory Corporation (NEROC), a consortium of nine educational institutions, on behalf of the Massachusetts Institute of Technology, which owns the facility. The existing antenna is being replaced with an improved version capable of working at wavelengths as short as 2 mm, expected to be in operation in 2012.
