IMAGE RELEASE: Cosmic Lens Reveals Faint Radio Galaxy

Astronomers using the VLA took advantage of the gravitational lensing provided by a distant cluster of galaxies to detect an even more-distant galaxy that probably is the faintest radio-emitting object ever found.

IMAGE RELEASE: Galaxies in the Perseus Cluster

New VLA images show how the crowded environment of a cluster of galaxies affects the individual galaxies, helping astronomers better understand some of the complex details of such an environment.

NRAO Contest Winners Illustrate Diverse Cosmic Phenomena

Winners in NRAO’s VLA 40th Anniversary Image Contest are from around the world, and their works illustrate a fascinating variety of celestial objects. Entries combined observational data from the VLA with data from optical, infrared, and X-ray telescopes, and from computer simulations.

A Weakened Black Hole Allows its Galaxy to Awaken

Astronomers have found the first example of a galaxy cluster where large numbers of stars are being born at its core. The discovery revealed new details of how supermassive black holes affect their host galaxies.

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.
