The U.S. National Science Foundation National Radio Astronomy Observatory (NSF NRAO) invites the public to the U.S. National Science Foundation Very Large Array (NSF VLA) for its annual Fall Open House on Saturday, October 11, 2025, from 9:00 a.m. to 4:00 p.m. This free, family-friendly event offers a rare chance to explore one of the world’s most iconic astronomical observatories through guided tours, talks by experts, hands-on learning activities, and more. 

The U.S. National Science Foundation National Radio Astronomy Observatory (NSF NRAO) has begun a major upgrade to the NSF Very Long Baseline Array (NSF VLBA) with the development and installation of state-of-the-art ultra wideband receivers capable of operating across the frequency range of 8 to 40 gigahertz (GHz). This new technology, first prototyped by NRAO in collaboration with NASA’s Jet Propulsion Laboratory (JPL), and tested on the NSF VLBA’s Owens Valley station, promises to significantly expand the scientific capabilities of the NSF VLBA.
