NRAO Mission Statement

The National Radio Astronomy Observatory enables forefront research into the Universe at radio wavelengths. In partnership with the scientific community, we:

  • provide world leading telescopes, instrumentation, data and expertise;
  • train the next generation of scientists and engineers;
  • advance broader, equitable, inclusive participation in science and engineering;
  • and promote astronomy to foster a more scientifically literate society.

About Our Facilities, People, and More

The NRAO operates three state-of-the-art radio telescope facilities for use by the scientific community, regardless of institutional or national affiliation: (1) the international Atacama Large Millimeter/submillimeter Array (ALMA), (2) the Karl G. Jansky Very Large Array (VLA), and (3) the Very Long Baseline Array (VLBA). Access to ALMA observing time by the North American astronomical community is enabled through the North American ALMA Science Center (NAASC).

The NRAO collaborates with the university astronomy community to develop new instrumentation and technology, and helps train the next generation of scientists through its student, co-op, postdoctoral, and Fellowship programs. A new data management system will soon improve every astronomer's access to NRAO data products for research and education.
