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.

New Receivers Achieve First Light, Set Record for Observational Capabilities at ALMA
A new set of receivers installed on antennas at the Atacama Large Millimeter/submillimeter Array (ALMA) have achieved first light. With it, they set a new record for the longest wavelengths visible with the radio array. The achievement has opened a window on the Universe previously inaccessible at the telescope, thanks to an international team of engineers, including engineers from the National Radio Astronomy Observatory (NRAO).
