What Would Happen if SgrA* Became Active?

When a black hole becomes more active it behaves much like “active galactic nuclei”, or AGN, found quite frequently…

Most theorists believe that a neutron star that surpasses the Tolman-Oppenheimer-Volkoff (TOV) mass limit will collapse directly into a…

By combining the signals from multiple telescopes radio astronomers are able to produce images or “pictures”, such as the…

Yes. Light is redshifted to longer wavelengths when it interacts with a black hole. This redshifted light, though, travels…

I don’t believe that radio astronomical measurements can distinguish between neutron star and black hole tidal disruption events. I…

The amount of mass that a typical black hole consumes over time is much smaller than its total mass,…

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.
