![]() ![]() We cultivate excellence, deliver value, enhance education, and engage the public. 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."ĪUI collaborates with the scientific community and research sponsors to plan, build, and operate cutting-edge facilities. Like eyeglasses, the lenses bend, or refract, light passing through them. ![]() NRAO also provides both formal and informal programs in education and public outreach for teachers, students, the general public, and the media. A telescope using a lens for its main optical element is called a refracting telescope. 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 telescopes are open to all astronomers regardless of institutional or national affiliation. ![]() What is the diagram telescope Telescopes work by collecting a lot of light and then use mirrors (Reflecting telescopes) or lenses (Refracting telescopes) to focus that light, i.e. Orbiting telescopes are used for other wavelengths. Earth-based telescopes can only detect visible light, some UV and IR and radio waves. The first observations were done with unaided eyes only. Over the history of astronomical observations, we have learned to employ and trust technology to help us study the sky. Operated under cooperative agreement by Associated Universities, Inc.įounded in 1956, the NRAO provides state-of-the-art radio telescope facilities for use by the international scientific community. What are the parts of a telescope Lenses. Telescopes for other Wavelengths Our atmosphere absorbs gamma-rays, X-rays, most UV and Infrared light. The involved telescopes also change their relative positions with respect to the target due to the Earth’s rotation covering larger parts of the Earth-sized mirror.
