The Extremely Large Telescope is astronomy's next big thing

A telescope the size of a stadium is rising in the Chilean desert. A trailblazing predecessor On the crest of the hill beside the residence stands the Very Large Telescope or VLT: the existing top-of-the-range "eye on the sky" run by the ESO. "Each single observation with the ELT is going to be mind blowing — something that has never been seen with such depth, with such granularity … It's going to allow us not just a step forward, but a jump." Each of the VLT's four lasers creates its own artificial "guide star". This "base camp" is tucked into the shoulder of Cerro Armazones: the mountain whose peak was levelled with dynamite to make way for the ELT's foundations.
