On Saturday the 26th of September 2026, the Telegrafenberg will welcome visitors for an open day from 12 pm to 5 pm. The Alfred Wegener Institute (AWI), Potsdam Institute for Climate Impact Research (PIK), GFZ Helmholtz Centre for Geosciences and the Leibniz Institute for Astrophysics Potsdam (AIP) invite the public to get a close-up look at the ‘Albert Einstein’ Science Park and the top-level research carried out there.

Surrounded by historic buildings, ancient trees and modern research facilities, guests can look forward to an exciting discovery from the Earth’s core to the wonders of the universe. Scientists from all four institutes will offer insights into their work and demonstrate how research in Potsdam is helping to answer the big questions of our time.

On this day, the AIP offers the opportunity to explore two of the Telegrafenberg’s most famous landmark buildings. Researchers will be presenting historical exhibits in the Great Refractor and demonstrating the world’s fourth-largest refracting telescope.

The Einstein Tower can also be visited as part of the open day. Visitors will be given an insight into the fascinating history and current state of solar research and learn more about the observatory’s significant contribution to the experimental verification of Albert Einstein’s theory of relativity. Due to the space limitations of this historic building, the number of people allowed in the Einstein Tower at any one time is limited to a maximum of 20. Consequently, there may be waiting times when visitor numbers are high.

The open day will be complemented by talks and presentations offering fascinating insights into the latest research being carried out at the four host institutes. The AIP, together with its partner institutes, looks forward to welcoming a large number of visitors.

The Leibniz Institute for Astrophysics Potsdam (AIP) is dedicated to astrophysical questions ranging from the study of our sun to the evolution of the cosmos. The key areas of research focus on stellar, solar and exoplanetary physics as well as extragalactic astrophysics. A considerable part of the institute's efforts aims at the development of research technology in the fields of spectroscopy, robotic telescopes, and e-science. The AIP is the successor of the Berlin Observatory founded in 1700 and of the Astrophysical Observatory of Potsdam founded in 1874. The latter was the world’s first observatory to emphasize explicitly the research area of astrophysics. The AIP has been a member of the Leibniz Association since 1992.
