The largest ground-based telescope is now being built on the top of Mauna Kea in Hawaii. The Thirty Meter Telescope (TMT) is a new class of extremely large telescopes that will allow us to see deeper into space and observe cosmic objects with unprecedented sensitivity. The TMT International Observatory LLC (TIO), a non-profit organization, was established in May 2014 to carry out the construction and operation phases of the TMT Project. The Members of TIO are Caltech, 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. Major funding has been provided by the Gordon & Betty Moore Foundation. Please join Tony Darnell and Christian Ready as they discuss the status of this project with Dr. Christophe Dumas, TMT Observatory Scientist & Head Operations Department.
