Warsaw University Observatory

About

The Astronomical Observatory of the University of Warsaw is one of the most distinguished astronomical institutions in Poland, with a history spanning nearly two centuries. Founded in 1825, its historic building is a beautiful classical edifice located within the Botanical Garden of the University of Warsaw. While its original observation domes are now purely decorative, the institution's scientific work is anything but. Today, the observatory is a vibrant and highly respected research institute, leading or participating in a wide array of international projects. Its reputation is particularly strong in the field of modern astrophysics, where it operates two large-scale, long-term sky surveys: OGLE (Optical Gravitational Lensing Experiment) and ASAS (All-Sky Automated Survey). These groundbreaking projects have been instrumental in the discovery of exoplanets and in research on dark matter, gravitational microlensing, and variable stars. Although the main observatory building no longer hosts active telescopes for research, the institute maintains a northern station in Ostrowik for educational purposes and, more importantly, a southern observing station at the world-renowned Las Campanas Observatory in Chile.
