What is TMT?

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. With its 30 m prime mirror diameter, TMT will be three times as wide, with nine times more area, than the largest currently existing visible-light telescope in the world. This will provide unparalleled resolution with TMT images more than 12 times sharper than those from the Hubble Space Telescope. When operational, TMT will provide new observational opportunities in essentially every field of astronomy and astrophysics.  Observing in wavelengths ranging from the ultraviolet to the mid-infrared, this unique instrument will allow astronomers to address fundamental questions in astronomy ranging from understanding star and planet formation to unraveling the history of galaxies and the development of large-scale structure in the universe. Check out the TMT Timeline to find out the current stage of TMT development. See a comparison between TMT and other upcoming extremely large telescopes.

What will TMT Explore?

TMT will be a unique tool for probing many outstanding open questions in astronomy. Its adaptive optics and spectroscopic capabilities will allow astronomers to explore the mysterious period in the life of the universe when the first stars and galaxies were formed, providing information about the nature of "first-light" objects and their effects on the universe's evolution. TMT will also observe the formation and development of the large-scale structures by looking at faint distant galaxies and the intergalactic medium, providing information on the physics of the early universe and the nature of dark matter that are inaccessible using any other techniques. TMT's high resolution will extend scientists'  capability to detect and investigate black holes that reside in the center of many distant galaxies, as well as study in detail the black hole in the center of our own Milky Way.  TMT will also play a very important role in advancing our knowledge of  the physical processes that lead to star and planet formation. TMT will be able to characterize and study  the properties of exoplanets leading us closer to finding out if life exists beyond the Earth. Finally, the advanced capabilities of the TMT will very likely lead to discoveries that we cannot anticipate and scientific impact far beyond what we envision today.

Who is building TMT?

The Thirty Meter Telescope is being designed and developed by the TMT International Observatory LLC (TIO). The TIO is a non-profit international partnership between the California Institute of Technology, the University of California, the National Institutes of Natural Sciences of Japan, the National Astronomical Observatories of the Chinese Academy of Sciences, the Department of Science and Technology of India, and the National Research Council (Canada). The Association of Universities for Research in Astronomy (AURA) is a TIO Associate and major funding for TMT has been provided by the Gordon & Betty Moore Foundation. The TIO will also run the TMT operations once the telescope is completed.

Our Story So Far...

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. Community outreach and engagement have been important to TMT from the start. Over the last 10 years, the project has held more than 20 public meetings, participated in numerous one-on-one meetings and group presentations, and has engaged in open dialog and meaningful discussions with community members and stakeholders to better understand the island’s issues as well as the cultural and natural significance of Maunakea. TMT has diligently followed the state’s laws, procedures and processes in its efforts to build TMT on Maunakea, including the preparation of a very extensive environmental impact statement. Over the last few years, TMT has experienced several unforeseen challenges, starting with the halting of its official groundbreaking ceremony by protestors in October 2014. Subsequent protests on the mountain prevented the start of construction on two separate occasions. On Thursday, September 28, 2017 the State Board of Land and Natural Resources (BLNR) announced its decision to grant the Conservation District Use Permit to the University of Hawaii – Hilo to build TMT on Maunakea. TMT is now assessing its next steps. TMT is also awaiting resolution on the state’s consent to the University of Hawaii’s sublease to the TMT International Observatory. The issue is currently with the Hawaii State Supreme Court. Much more information about TMT and Hawaii can be found on a dedicated website at http://www.maunakeaandtmt.org/.
