High up In the Atacama Desert, 5,000m (16,400ft) above sea level is one of the world's largest astronomical projects - the Atacama Large Millimetre/sub-millimetre Array (Alma).
The project uses radio telescopes to pick up wavelengths of light that are invisible to the human eye and may help reveal the origins of the Universe.
