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.

Io’s volcanism seen by The University of Tokyo Atacama 1-m Telescope (pressreleased: 2014/6/19)
Io, one of the most remarkable moons of Jupiter, is also known as the most volcanically active body in the solar system. Its volcanism is variable, and has been monitored by detecting near infrared thermal emissions since Io’s volcanic thermal emission peaks at near infrared wavelengths. However, there is significant difficulty in near infrared observations of Io ...more>>
