The Caltech Submillimeter Observatory (CSO) has been completely removed from Maunakea in Hawai‘i, including its foundation, dome, and buildings, as part of the decommissioning process initiated in 2015. The site will be monitored for three years to observe natural repopulation. The telescope, operational from 1987 to 2015, made significant discoveries in submillimeter wavelengths. Its components will be repurposed in Chile as the Leighton Chajnantor Telescope, named after its inventor, Robert B. Leighton. The new telescope will focus on observing cosmic eruptions and distant galaxies. The decommissioning was funded by the Gordon and Betty Moore Foundation and Caltech, with support from the Heising-Simons Foundation. Caltech expressed gratitude to the people of Hawai'i for their collaboration during the decommissioning process. For more detailed information, visit the CSO website.
