The first European antenna for the Atacama Large Millimeter/sub-millimeter Array (ALMA) reaches new heights, seen here being transported to the observatory’s Array Operations Site (AOS). The 12-meter diameter antenna arrived at the Chajnantor plateau, 5000 meters above sea level, to join antennas from the other international ALMA partners, bringing the total number at the AOS to 16. Although this sounds like just another number, 16 is the number of antennas specified for ALMA to begin its first science observations, and is therefore an important milestone for the project.
