Photographing the ALMA radio astronomy antennae. ALMA (Atacama Large Millimetre/sub-millimetre Array) is an array of 66 radio antennae located at an elevation of 5000 metres on the arid Chajnantor plateau in the Chilean Andes. Data from the separate antennae are combined by interferometry, making it one of the most powerful telescopes in the world. The Milky Way stretches across the sky, and the Small Magellanic Cloud is visible on the lower right. A photographer equipped with oxygen cylinder prepares to shoot the scene.
