The Sphinx Laboratory is part of the Sphinx building and belongs to the Sphinx AG Jungfraujoch, a subsidiary company of the Jungfraubahn Holding AG. It is at the free disposal of the Foundation. It has an astronomical dome, two large and two small laboratories, a workshop, two terraces for scientific experiments, and a weather observation station. The observation instrument in the astronomical dome is a 76 cm telescope which is no longer in use. Many long-term experiments are permanently installed in the Sphinx laboratories. Space for other projects and campaigns is available upon request.
