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).
