The Thirty Meter Telescope is a new class of extremely large telescopes that will allow us to see deeper into space and observe cosmic objects with unprecedented sensitivity.
TMT will be a unique tool for probing many outstanding open questions in astronomy.
The Thirty Meter Telescope is being designed and developed by the TMT International Observatory LLC (TIO).
TMT scientists selected Maunakea in July 2009 after a rigorous five-year campaign spanning the entire globe that measured virtually every atmospheric feature that might affect the performance of the telescope.
A new research frontier in astronomy and astrophysics will open in the mid-2020s with the advent of ground-based extremely large optical-infrared telescopes (ELTs) with primary mirrors in the 20-m – 40-m range. U.S. scientific leadership in astronomy and astrophysics will be significantly enhanced if the broad U.S. community can take advantage of the power of these new ELTs. In that context, the National Science Foundation’s (NSF) National...
Members of the TMT Science Advisory Committee (SAC) met in Pasadena on April 9&10, 2018 for their quarterly gathering. SAC representatives reported on their respective activities for the TMT project and discussed top-level requirements for TMT’s suite of science instruments.
The TMT International Observatory (TIO) Board of Governors at its meeting this week deferred a decision on whether to continue towards building the Thirty Meter Telescope in Hawaii, or to consider the alternative in the Canary Islands.
Pasadena, March 16, 2018 - The conceptual design and scope of TMT’s Refrigerant Cooling System (REFR), which was executed and developed by a close Chinese-North American collaboration, successfully passed a recent conceptual design review. This system will be used to provide cooling to electronics enclosures mounted on the telescope structure. The system also maintains several TMT instrument enclosures at subzero temperatures to reduce thermal...
Pasadena, CA - March 8, 2018 - Future users of the Thirty Meter Telescope are now preparing studies of the science instruments that will be deployed after the telescope's first-light instrumentation suite.
