Antennae Galaxies

Hard to believe that this was once a pair of spiral galaxies. Undergoing a violent merger, the well-named Antennae Galaxies are quite a spectacle to radio telescopes. In blue are the data from the VLA, showing the trails of hydrogen stripped from the outer arms of the two spirals. In orange and gold (inset) are the data from ALMA showing the areas of star formation caused by the collision of gas and dust clouds.

contract Media Use Policy

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.
