A giant radio telescope in Chile has received the last piece of its 66-antenna array, a special delivery that will help the observatory peer into deep space better than ever.

The antenna was delivered Monday (Sept. 30) to the Atacama Large Millimeter/submillimeter Array (ALMA), and is expected to be installed by the end of the year. ALMA has been in operation for years, adding antennas as it goes. With this last antenna one — No. 66 of the dozens provided by Europe, North America and Asia — the telescope will reach its maximum sensitivity.
