A view of the Zodiac

ALMA stand for Atacama Large Millimetre/submillimetre Array and is the most powerful telescope for observing the cool Universe, molecular gas and dust. However, ALMA is an array of 66 antennas in the shape of large metallic satellite dishes and does resemble a typical telescope. ALMA is composed of a main array of fifty antennas measuring 12 metres in diameter. This array is complemented by an additional four 12-metre and twelve 7-metre antennas arranged in a more compact array. The antennas can be moved around and are positioned on top of different concrete foundation pads. With maximum distances varying between 120 metres and 16 kilometres, ALMA has a powerful variable zoom.

ALMA operates at wavelengths of 0.32 to 3.6 mm, about one thousand times longer than visible light. Radiation in these wavelengths open a window into the cold Universe. However, the Earth's atmosphere contains water vapour which absorb signals from space. This is why ALMA is built at the 5000-m high and dry Chajnantor plateau in the Atacama Desert, Antofagasta Region, Chile.
