The last 12 meter (40 ft) antenna has arrived at the Atacama Large Millimeter/submillimeter Array (ALMA), pushing the project closer to its full operational potential. The final antenna was supplied by the European side of the venture, and completes the 66 dish array stretching across the Chajnantor Plateau in Chile's Atacama Desert. The telescope, which was inaugurated in March 2013, has already made a number of significant discoveries despite its incomplete nature.
