>The Sphinx Observatory 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.

>Switzerland’s Sphinx Observatory has been called the Top of Europe, and with good reason: At 11,716 feet above sea level, the mountaintop building, which was completed in 1937, is the continent’s highest man-made structure. “The observatory is on the craziest spot you can think of,” Finnish photographer Konsta Punkka says of the complex, which houses astronomical and meteorological domes, a telescope, and extreme-environment laboratories. Despite its precarious perch, the Sphinx is surprisingly accessible: Visitors arrive year-round by train at Jungfraujoch, Europe’s highest railway station, and then continue ascending via an elevator built into the hollowed-out mountain. Capturing this shot, however, proved trickier. “Using a drone was a very difficult task at this high altitude—close to glaciers, with the crazy winds,” Punkka says, “but I had this sunrise shot in mind already before I visited, so I had to get it.” While it may look like a simple landscape photo, Punkka has referred to this image as “my kind of a selfie.” See if you can spot him, arms outstretched, on the observation deck.
