Colossal telescope given go-ahead

Summary: The European Extremely Large Telescope (E-ELT) is given the go ahead to be built. It will have a primary mirror some 40m in diameter, and will be built on top of a mountain in Chile. When completed it will be the largest optical telescope in the world. It will see in visible and near-infared. It will hopefully uncover some of the mysteries surrounding dark energy.
