Zimmerwald Observatory

Zimmerwald Observatory is an astronomical research station in the Swiss Alps that focuses on satellite tracking and asteroid observation using precise measurement techniques. The facility operates modern telescopes and laser-ranging equipment that gather detailed data about objects in space.

The station began operations in 1956 with basic telescopic equipment for sky observation and has evolved into a modern center for satellite tracking over the decades. Today it represents the growth of Swiss contributions to international space research.

The observatory supports research collaboration among several European universities and helps train students in astronomy and space science. You can see here how scientists work together on international projects to advance our understanding of space.

The station sits on a mountain near Bern and viewing is best during clear nights when the sky is dark. Visitors should wear sturdy footwear and be prepared for changeable alpine weather conditions.

This observatory discovered a comet from which NASA brought particles back to Earth, a rare scientific legacy. These comet samples represent the far-reaching impact this station has had on space exploration.
