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.

What will TMT Explore?

TMT will be a unique tool for probing many outstanding open questions in astronomy.

Who is building TMT?

The Thirty Meter Telescope is being designed and developed by the TMT International Observatory LLC (TIO).

Our Story So Far...

The Board of the Thirty Meter Telescope 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.
