language

description Thirty Meter Telescope Overview

The Thirty Meter Telescope is a planned ground-based astronomical observatory centered on a segmented primary mirror 30 meters in diameter. Its design covers wavelengths from the near-ultraviolet through the optical and into the mid-infrared, with adaptive optics intended to correct for atmospheric distortion. It is conceived for research including the formation of stars and galaxies, exoplanets, black holes, and the early universe, with Mauna Kea in Hawaii selected as its intended site.

insights Ranking position

Thirty Meter Telescope ranks #102 of 271 in the Observatory ranking, behind Lowell Discovery Telescope, ahead of Kitt Peak National Observatory.

help Thirty Meter Telescope FAQ

Why does the Thirty Meter Telescope need a 30-meter mirror?

A larger primary mirror gathers far more light than today's 8 to 10-meter telescopes and can distinguish much finer detail. TMT is intended to study targets ranging from exoplanet atmospheres to the earliest galaxies.

Is the Thirty Meter Telescope already operating?

No. TMT remains a planned observatory, and construction at its intended Maunakea site has not proceeded because of legal, cultural and political opposition.

Why is the proposed Maunakea location controversial?

Maunakea offers exceptional astronomical conditions but is also a sacred landscape in Native Hawaiian culture. Protectors have opposed additional construction and challenged how scientific institutions obtained and exercised authority on the mountain.

How would TMT differ from the Extremely Large Telescope in Chile?

TMT is designed around a 30-meter segmented mirror, while ESO's Extremely Large Telescope uses a larger 39-meter primary mirror. They are separate international projects planned for different hemispheres, giving them access to different portions of the sky.
