CfA Facilities
Headquarters Staff Locations
Since creation of the CfA in 1973, most staff members have been headquartered in Cambridge, Massachusetts. However, sites in Arizona and Hawaii, which house SAO's major ground-based observational facilities, are also primary locations for CfA staff.
Fred Lawrence Whipple Observatory Ground-Based Telescopes
For nearly 400 years, astronomers have used ground-based optical telescopes to explore the universe. Since the 1930s, radio antennas have captured light from celestial sources. The CfA currently operates telescopes in Arizona and Hawaii and is a partner in facilities in Chile. CfA is also a partner in the GMT consortium, a project to build the world's largest optical/infrared telescope.
Chandra Observatory Space-Based Telescopes
Space observatories enable astronomers to observe ancient light unimpeded by the Earth's atmosphere. Aside from providing a clearer view at optical and infrared wavelengths, these instruments allow observations at X-ray and ultraviolet wavelengths where the atmosphere is opaque. In addition to constructing satellite instrumentation for studying the Sun, CfA scientists and engineers designed and built major instruments for the Chandra and Spitzer satellites. Today, several groups are studying approaches for the next generation of space observatories.
Centers Centers
Facilities that serve the scientific community by hosting workshops and seminars and by providing opportunities for visiting scientists to conduct or participate in collaborative research are also located at CfA in Cambridge. Among them are the Institute for Theoretical Atomic, Molecular and Optical Physics (ITAMP), the Institute for Theory and Computation (ITC), and the Center for X-ray Technology (CXT).
Engineering Engineering
An organization of uniquely skilled engineers, working in sophisticated assembly and test laboratories in Cambridge provides CfA scientists with the unusual opportunity to design and build both space and ground-based telescopes and other research instruments in-house.
