Winer Observatory

Winer Observatory is an astronomical research facility in the desert of southeastern Arizona with multiple telescopes on a 20-acre site with dark skies. The dry weather conditions and distance from cities make it ideal for sky observation and scientific measurements.

The observatory was founded in 1983 as a nonprofit organization and named after a physics professor who inspired its director. This establishment marked the beginning of a long history of sky observation in this region.

Visitors come to observe the night sky and participate in research programs supported by partnerships with universities around the world. This shared interest in astronomy brings together people from different countries in a location far from city lights.

The facility provides access to an all-sky camera system for meteor observation and allows visitors to participate in research projects. It is located about 50 miles southeast of Tucson and is best reached on nights with clear skies.

A specialized telescope at the facility has contributed to the discovery of more than 30 exoplanets through systematic sky surveys. These findings show how important this location is for modern research into other planetary systems.
