LL/44223
Antenna number 16th of the Atacama Large Millimeter/submillimeter Array (ALMA) has reached the heights of the Chajnantor plateau after having been transported to the observatory's Array Operations Site (AOS). The 12-meter diameter antenna, which was a European deriverable, has arrived at 5,000 meters above sea level where it joined antennas from the North American and the East Asian ALMA partners. 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. Soon, astronomers will begin conducting new scientific research with ALMA.
