What is the TAO project?

The TAO project is a plan to build a world-top infrared-optimized telescope with a 6.5m diameter aperture on the summit of Cerro Chajnantor at Atacama in north Chile. This telescope will be dedicated to understand the nature of the Universe and the origin of life. The TAO project is promoted by Institute of Astronomy (IoA), the University of Tokyo with collaboration with the Department of Astronomy, the University of Tokyo, many other Japanese facilities including the National Astronomical Observatory, ISAS/JAXA, and other universities as well as partnership with the Department of Astronomy, the University of Chile.
