World’s Highest Observatory Inaugurated in Chile by University of Tokyo

Introduction to the Observatory

The University of Tokyo has inaugurated the Atacama Observatory (TAO) in Chile, officially recognized as the highest observatory in the world by Guinness World Records. Situated at an astounding 5,640 meters above sea level on Cerro Chajnantor in the Antofagasta Region, TAO represents a pinnacle of human achievement in astronomical research.

Cutting-edge 6.5-meter Optical-Infrared Telescope

At the core of TAO is a 6.5-meter optical-infrared telescope. This state-of-the-art instrument is designed to delve into the mysteries of the cosmos, offering unprecedented insights into the universe’s fundamental nature. Its advanced capabilities will significantly enhance our understanding of astronomical phenomena.

Exceptional Location for Astronomical Observation

The location of TAO on Cerro Chajnantor was strategically chosen for its superior atmospheric conditions. The minimal water vapor at this high altitude allows for exceptional clarity in observing mid-infrared wavelengths, which are usually absorbed at lower elevations, providing an unparalleled observational advantage.

Overcoming High-Altitude Construction Challenges

The construction of TAO was a monumental task that took 26 years of meticulous planning and execution. The project’s director, Takashi Miyata, highlighted the technical and political challenges encountered. The extreme altitude and harsh conditions required innovative solutions and collaboration across various fields.

Ensuring Safety Against Altitude Sickness

To mitigate the risks of altitude sickness for workers and astronomers, especially during nighttime operations, a base facility was established in San Pedro de Atacama, around 50 kilometers from the summit. This facility supports remote telescope operation, ensuring the safety and well-being of the personnel.

Proximity to ALMA for Collaborative Research

TAO is located near the ALMA (Atacama Large Millimeter/submillimeter Array) radio telescope, fostering a collaborative hub for international astronomical research. This proximity enhances cooperation and synergy among global scientific communities, paving the way for groundbreaking discoveries.


The inauguration of TAO by the University of Tokyo marks a significant milestone in astronomical exploration. This advanced observatory is set to play a crucial role in expanding our knowledge of the universe, contributing to numerous scientific breakthroughs in the years to come.
