World's largest telescope underway, scientists definitely observe big bang

Once again astronomers are observing formative explosions, but this time a little bit closer to home. Three million cubic feet of planet earth is being blasted from the Chilean Andes as work on what will be the world's largest telescope begins. The location is the Carnegie Institution's Las Campanas Observatory, and the project is a collaboration between South Korean, Australian and American institutions to create the Giant Magellan Telescope. The first mirror segment is just being completed, and is so precise, it matches its optical prescription to within a millionth of an inch. The project will cost $700 million once complete, small change we say for a chance to glimpse light from the edge of the Universe.
