National Astronomical Observatory of Japan



Based on the scientific and engineering success of 8.2-meter Subaru Telescope, astronomers are preparing to begin construction of the Thirty Meter Telescope (TMT) as an international science project. With an aperture of 30m, TMT will have more than 10 times as much light-gathering power as the Subaru Telescope, and boasts more than 10 times the resolution of the Hubble telescope. Such a telescope, together with other next-generation facilities based on ground and in space, will play an essential role in the 2020s to deepen the human perception of the structure and evolution of the Universe, and the origins of stars, planets and life. National Astronomical Observatory of Japan (NAOJ) is responsible for the project in Japan.
