The Thirty Meter Telescope (TMT) - soon to be the world's widest eye on space - has got the go-ahead for construction on the summit of Mauna Kea, Hawaii. Most of Mauna Kea is below sea level. When measured from its oceanic base, its height is 33,500 ft (10,200 m)—more than twice Mount Everest's base-to-peak height. The sacred mountain is about one million years old --long past the most active shield stage of life hundreds of thousands of years ago--providing a stable platform for what will will be the world’s most advanced and capable ground-based optical, near-infrared, and mid-infrared observatory. The TMT will integrate the latest innovations in precisions control, segmented mirror design, and adaptive optics. The giant eye will enable groundbreaking advances in a wide range of scientific areas, from the most distantreaches of the Universe to our own Solar System. TMT will allow astronomers to explore virtually every aspect of this picture, from inflation to exoplanets. The resolution and sensitivity provided by its large aperture and adaptive optics systems, combined with a flexible and powerful suite of instruments, will enable astronomers to address many of the most fundamental questions ofthe coming decades. via The Daily Galaxy.
