The National Radio Astronomy Observatory (NRAO) is an American research organization dedicated to radio astronomy. It is a facility of the National Science Foundation, operated under a cooperative agreement by Associated Universities, Inc. It was founded in 1956.
NRAO operates a suite of telescopes including:
- The Atacama Large Millimeter/submillimeter Array (Atacama Desert, Chile)
- The Very Long Baseline Array (Various locations across USA)
- The Very Large Array (New Mexico, USA)
Any scientist can apply to use these telescopes. The process is fairly typical: Submit an application for telescope time, presenting your research proposal and explaining why it is worthy. Like all research facilities, time is limited and you'll be competing against other research proposals.
