About Five College Radio Astronomy Observatory
Known as FCRAO, the observatory was founded in 1969 by the Five College Astronomy Department, a partnership of the University of Massachusetts Amherst, Amherst College, Hampshire College, Mount Holyoke College, and Smith College. From the start, it emphasized research, technology development, and the training of both graduate and undergraduate students.
History
FCRAO's initial instrument was a customized low-frequency antenna built to search for pulsars in the galaxy. Instrumentation developed in the observatory's labs contributed to the discovery of the binary pulsar system PSR B1913+16 by Joseph Taylor and Russell Hulse, work for which they received the 1993 Nobel Prize in Physics.
Telescopes & research
The original antenna was replaced in 1976 by a 14-meter radome-enclosed millimeter-wave telescope, which became the observatory's primary research instrument for radio astronomy.
Location & getting there
The observatory sits on a peninsula in the Quabbin Reservoir, New Salem, Massachusetts, United States, at 306 meters elevation, within the North America region on Star Register.
