ATACAMA DESERT, Chile, Nov 1 (Reuters) - In Chile's dry Atacama desert, stargazers are scanning the clear night skies to detect the existence of life on other planets and study so-called 'dark energy,' a mysterious cosmic force thought to be driving the accelerating expansion of the universe.Ĭentral to the race to peer into distant worlds is the Giant Magellan Telescope (GMT), a $1.8 billion complex being built at the Las Campanas observatory and which will have a resolution 10 times higher than the Hubble space telescope.
