About the Subaru Telescope

The Subaru Telescope is a large optical-infrared telescope located near the summit of Maunakea, on Hawai'i Island. The primary mirror is one of the world's largest monolithic mirrors, with an aperture of 8.2 meters. This large light collecting power enables it to capture even the faintest light from celestial objects. A major feature of the Subaru Telescope is its ability to mount instruments at the prime focus where the field of view is overwhelmingly wide compared to other very large telescopes. In addition, the Subaru Telescope is equipped with various innovations to obtain sharp images of celestial objects from the light it collects, such as high-performance adaptive optics, making the Subaru Telescope's high resolving power one of the highest among the world’s very large telescopes. This performance has been achieved through careful selection of the telescope's site and the use of state-of-the-art technology.
