Scientific Goals and Missions - Subaru Ground Layer Adaptive Optice (GLAO) Project


The Subaru Ground Layer Adaptive Optics (GLAO) project is to provide a unique capability for Subaru Telescope to realize high spatial resolution observations over a wide field coverage, aiming to pioneer new observational parameter spaces that bring innovative and valuable outcomes in the exploration of the universe at the optical and infrared wavelengths.


The missions of this project are to develop and implement Ground Layer Adaptive Optics (GLAO) system into Subaru Telescope in order to sustain a state-of-the-art observatory and facilitate science for broader communities, leading the design of new scientific requirements for the coming decade and more in Astronomical observations at high spatial resolution over wide filed coverage.

Primary Scientific Goals

The primary scientific goal of this project is to realize wide-field and high spatial resolution observation at Subaru telescope, aiming to perform square-degree scale surveys in order to reveal the birth, growth, and death of galaxies across cosmic time and environment, including a systematic spectroscopic survey and a narrow-/medium-/broad-band imaging survey at the near-infrared wavelength.

Target Date

End of March 2026
