Kölner Observatorium für SubMillimeter Astronomie

The Kölner Observatorium für SubMillimeter Astronomie features a primary mirror of 3 meters and a secondary mirror of 0.27 meters at 3,135 meters elevation.

The observatory began operations in 1985 at the southern tower of Gornergrat Kulm Hotel and continued its astronomical research until its decommissioning in 2010.

Scientists from the Universities of Cologne and Bonn collaborated at this facility to conduct research on interstellar medium and molecular clouds.

The telescope operated with heterodyne receivers covering frequencies from 210 to 820 GHz, enabling observations of various astronomical phenomena through submillimeter wavelengths.

After serving its mission in Switzerland, the telescope relocated to Yangbajain, Tibet, at 4,300 meters elevation, where it received the new name CCOSMA.
