Beyond The Visible: The Story of the Very Large Array

This 24-minute production explores the synergies of technology and human curiosity that power the world’s most productive radio telescope.

Into Deepest Space: The Story of ALMA

this 52-minute public television documentary reveals the motivations, struggles and ultimate triumphs of the people designing and building the most elaborate ground-based astronomical observatory ever, the Atacama Large Millimeter/submillimeter Array (ALMA).

Building the 140-foot Telescope at Green Bank

The world’s largest polar-aligned telescope was a challenge to design, deliver, and assemble. Here is the story of how it was finally erected in Green Bank, West Virginia in 1965.

ALMA Discovers Proto Super Star Cluster

Animation of ALMA data depicting dense cores of molecular gas in the Antennae galaxies. The yellow object at the center may be the first prenatal example of a globular cluster ever identified.

Animation of a Gravitational Lens Creating an Einstein Ring

Animation demonstrating how the gravity from a massive foreground galaxy can bend the light of a more distant galaxy. If the two galaxies line up just right, the result is a highly distorted image of the distant galaxy known as an Einstein ring. The radio image portion of the video is of galaxy SDP.81, which was imaged by ALMA as part of the telescope’s Long Baseline Campaign.

NGC 253: Why Starburst Galaxies Burst

Animation of ALMA data reveals a diffuse envelope of carbon monoxide gas (shown in red), which surrounds stellar nurseries — regions of active star formation (in yellow). By dissecting these regions with ALMA, astronomers are uncovering clues to the processes and conditions that drive furious star formation. The ALMA data are superimposed on a Hubble image that covers part of the same region.

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.
