The Atacama Large Millimeter/submillimeter Array (ALMA) in Chile has begun observing in a new range of the electromagnetic spectrum. This has been made possible thanks to new receivers installed at the telescope's antennas, which can detect radio waves with wavelengths from 1.4 to 1.8 millimeters -- a range previously untapped by ALMA. This upgrade allows astronomers to detect faint signals of water in the nearby Universe.
