ALMA Observatory Shutdown Impacts Scientist Worldwide.

March 26, 2023


The Atacama Large Millimeter Array (ALMA) Observatory in Chile has suspended all astronomical observation operations and taken its public website offline following a cyberattack on Saturday, October 29, 2022. Email services at the observatory are currently limited, and IT specialists are working toward restoring the affected systems.

The observatory is used by scientists of the National Science Foundation, the European Southern Observatory, the National Astronomical Observatory of Japan, and other groups from around the world, so any halt in its operations impacts multiple science teams and ongoing projects.
