Caltech Submillimeter Observatory


CSO

 

The Caltech Submillimeter Observatory (CSO) was formerly one of the world's premier facilities for astronomical research and instrumentation development at submillimeter wavelengths. The 10.4 m diameter telescope is housed in a compact dome at 4070 m altitude near the summit of Maunakea, Hawai'i.  CSO ceased scientific operations in 2015.  It will be decommissioned and the site restored.
