'You really feel it when you've been here a long time... Sometimes my hands start to bleed because it's so dry here.'
It turns out, work can actually make you sick. All in the name of human discovery eh? The lightweight atmosphere provides astronomers with the perfect setting for looking into space. And now they're taking us even closer to the action, building the Atacama Large Millimetre/Submillimetre Array (Alma) telescope 5,000 metres above sea level, near the Bolivian border in the Andes mountain range. This incredible technology will allow these space invaders to see into half of the universe that was previously hidden by space dust (the solar variety, not the popping candy). Scary.
Seeing as I'm a lowly enthusiast, I'll leave it to a professional, John Richer, University of Cambridge lecturer and a project scientist for Alma, to explain:
"When a star forms, it forms in cold, dusty gas clouds. The moment it's formed it's shrouded in this dusty material, out of which only half of the light from a typical star escapes. Many other stars are formed in very dense clouds and their light is completely absorbed by the dust in these clouds."
The Alma telescope will be able to detect the radiation emitted by this dust when it is heated by nearby stars, therefore revealing previously unseen galaxies. When fully functional (completion is set for 2013), it is expected to unveil a new galaxy every three minutes, yet another show of the eternal human quest for knowledge and very impressive technological development.

In the mean time, watch the space.. literally.
