The Highest Observatory On Earth Sits Atop Chile’s Andes Mountains – And It’s Now Finally Open

The Japanese University of Tokyo Atacama Observatory (TAO) was unveiled as the highest astronomical site in the world, marking a significant milestone in astronomical research.

TAO’s prime location at 5,640 metres above sea level, atop Chile’s Cerro Chajnantor mountain, offers unmatched cosmic insights. It was created over 25 years ago and resulted from careful planning and teamwork. The University of Tokyo professor Yuzuru Yoshii led the observatory’s construction, which was fraught with complex political and technical obstacles.

Yoshii guaranteed safety at high altitudes by coordinating with local institutions and health authorities, consulting with Indigenous people, and negotiating with the Chilean government.

The observatory’s altitude and the area’s lack of moisture make it a prime location for infrared telescopes such as TAO. This technological wonder comprises a 6.5-meter telescope with two state-of-the-art instruments: MIMIZUKU and SWIMS. While MIMIZUKU explores the early beginnings of stars and galaxies, fanning hopes for ground-breaking discoveries, SWIMS seeks to solve the puzzles surrounding galaxy formation.

TAO researcher and University of Tokyo graduate student Riko Senoo emphasises how important astronomical observations are to improving scientific knowledge. Similarly, University of Tokyo research associate Masahiro Konishi hopes that TAO will encourage the next generation of astronomers to question generally existing paradigms and solve the mysteries of the cosmos.

Over ten years have passed since the inception of TAO, which started in 2006 with the construction of infrastructure and ended with the observatory’s recent opening. Before construction began, the project was named in a solemn ceremony that combined scientific aspirations with traditional regard.
