The Five College Radio Astronomy Observatory stood on a peninsula in the Quabbin Reservoir in New Salem, Massachusetts, on land once part of Prescott. Founded in 1969 by the Five College Astronomy Department, it united research, instrument development, and the training of undergraduate and graduate students. Its first customized low-frequency antenna searched for pulsars, and laboratory work there contributed to the instrumentation behind Joseph Taylor and Russell Hulse’s discovery of the binary pulsar PSR B1913+16, later honored with the 1993 Nobel Prize in Physics. In 1976, a 14-meter millimeter-wave telescope replaced the original instrument. As attention shifted to the Large Millimeter Telescope in Mexico, the site declined, and its telescope and control building were removed in 2011.
