ALMA telescope reaches new heights
23 September 2009: The ALMA (Atacama Large Millimeter/submillimeter Array) astronomical observatory has taken another step forward — and upwards. One of its state-of-the-art antennas was carried for the first time to the 5000m plateau of Chajnantor, in the Chilean Andes, on the back of a custom-built giant transporter. The antenna, which weighs about 100 tons and has a diameter of 12 metres, was transported up to the high-altitude Array Operations Site, where the extremely dry and rarefied air is ideal for ALMA’s observations of the Universe.
