Do Asteroids Emit Radio Signals?

-- | June 18, 2017

Question: Do Asteroids emit radio signals? — Ron

Answer: Asteroids are basically rocks floating around in our solar system. When asteroids absorb light from the Sun their surfaces heat-up. When their surfaces heat-up they re-emit light at longer wavelengths, through a process called black body emission, including infrared and radio wavelengths. This then allows us to see asteroids at radio wavelengths.

The National Radio Astronomy Observatory is a facility of the U.S. 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 U.S. 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.
