“US scientists have drawn up plans to build the largest telescope ever seen.

Its 30-metre-diameter mirror would be almost 10 times as big as those in the Keck telescopes in Hawaii, currently the world’s largest observatories.” —BBC If funded and without engineering glitches, the telescope, to be sited at anas-yet-undetermined location in Hawaii, Chile or Mexico, could see first light by 2012. There is also a more fanciful European Large Telescope Project planning a 100-meter ‘scope for a South American site.
