LARGEST SPACE OBSERVATORY OPENED
In a super-arid desert at an altitude of 5,000 meters, with almost no humidity or vegetation, the world's largest groundbased astronomy project opened for business on March 13, 2013, ready to probe the universe with unpre-cedented might. The Atacama Large Milli-meter submillimeter Array (ALMA) inChile is a joint effort among North Ameri-can, European and Asian agencies. "What is so very special about this place is that, right here above our heads, there is virtually no water vapour.
There is just so little that whatever light is emitted from a heavenly body, galaxy or star, it gets here with no interference," said Gianni Marconi, an astronomer with ALMA. "And this is the largest observatory that has ever been built," he added. As there is virtually no humidity to get in the way, ALMA's 66 antennas, ranging
in diameter from 7 to 12 metres, can glimpse at things in the darkest and remotest regions of the universe.
