While initially planned by institutions in North America, the proposed Thirty Meter Telescope (TMT) has grown into an ambitious multinational partnership involving institutes from Japan, China, India, in addition to the U.S. and Canada.

Japan’s interest in the next generation telescope dates back to the completion of the National Astronomical Observatory of Japan’s Subaru Telescope atop Maunakea in 1999, and Subaru’s subsequent campaign to look deep into the history of the Universe, using a unique wide field camera able to spot galaxies at 13 billion light years away. The success of this campaign—highlighted by the 2006 discovery of the most distant galaxy, IOK-1, which held the world record for five years—led to the enthusiastic support of Japan’s participation to TMT.

Building on the legacy of Subaru Telescope, Japan has assumed responsibility for designing and building the TMT structure, and providing 576 special glass blanks for the 30 meter primary mirror, with much of the work well underway in Japan.

Talk summary

In his presentation, Iye will discuss in detail the engineering and innovation involved in the building of the TMT, along with the challenges involved. He will also touch on some discoveries the TMT is projected to identify by the late 2020’s. These future discoveries are expected to include the history of the early Universe, when the first stars and galaxies were formed, detailed studies of extrasolar planets and their formation process, and the nature of dark matter and dark energy.


Masanori Iye received his doctor of science in astronomy at the University of Tokyo. He is now a professor emeritus of the National Astronomical Observatory of Japan, and currently serves as the Japan representative of the TMT project.

Among many awards, he is the winner of the Japan Academy Prize and the Imperial Medal with Purple Ribbon for Contributions to Astronomy. Professor Iye has been very active in supporting and expanding astronomy education in Japan, and was the director of three award-winning science video films.


Hosted by Planetarium Technician Emily Peavy, ‘Imiloa’s monthly Maunakea Skies program includes observational highlights of the current night sky over Hawai‘i, with the audience able to view prominent constellations and stars visible during this time of year.
