Gigantic telescope to be built in Hawai'i
Date: 23-Jul-09
Author: TMT Observatory Corporation
After careful evaluation and comparison between two outstanding candidate sites -- Mauna Kea in Hawai'i and Cerro Armazones in Chile -- the board of directors of the TMT Observatory Corporation has selected Mauna Kea as the preferred site for the Thirty Meter Telescope. The TMT will be the most capable and advanced telescope ever constructed.
When completed in 2018, the TMT will enable astronomers to detect and study light from the earliest stars and galaxies, analyze the formation of planets around nearby stars, and test many of the fundamental laws of physics.
To achieve these outstanding results, the TMT will integrate the latest innovations in precision control, segmented mirror design, and adaptive optics to correct for the blurring effect of Earth's atmosphere, enabling the TMT to study the Universe as clearly as if the telescope were in space. Building on the success of the twin Keck telescopes, the core technology of TMT will be a 30-meter primary mirror composed of 492 segments. This will give TMT nine times the collecting area of today's largest optical telescopes.

The TMT project is an international partnership among the California Institute of Technology, the University of California, and ACURA, an organization of Canadian universities. The National Astronomical Observatory of Japan (NAOJ) joined TMT as a Collaborating Institution in 2008.
