The National Radio Astronomy Observatory is a facility of the National Science
Foundation operated under cooperative agreement by Associated Universities, Inc.
Founded in 1956, the NRAO provides state-of-the-art radio telescope facilities
for use by the international scientific community. NRAO telescopes are open to
all astronomers regardless of institutional or national affiliation. Observing
time on NRAO telescopes is available on a competitive basis to qualified
scientists after evaluation of research proposals on the basis of scientific
merit, the capability of the instruments to do the work, and the availability of
the telescope during the requested time. NRAO also provides both formal and
informal programs in education and public outreach for teachers, students, the
general public, and the media. The National Science Foundation (NSF) is an
independent federal agency created by Congress in 1950 "to promote the progress
of science; to advance the national health, prosperity, and welfare; to secure
the national defense..." AUI collaborates with the scientific community and
research sponsors to plan, build, and operate cutting-edge facilities. We
cultivate excellence, deliver value, enhance education, and engage the public.
