A high-ranking delegation led by Dorothee Bär, Federal Minister of Research, Technology and Space in Gerrmany visited the Paranal Observatory of the European Southern Observatory (ESO) in Chile on 4 and 5 February 2026. The delegation included Markus Blume, Bavarian Minister of State for Science and the Arts, Thomas Reiter, Director General for Space and Security at the Federal Ministry of Research, Technology and Space, and Patrick Cramer, President of the Max Planck Society. The Leibniz Institute for Astrophysics Potsdam (AIP) was represented by Prof. Dr. Matthias Steinmetz, Scientific Director of the AIP and member of the ESO Council.
The delegation was welcomed by ESO Director General Xavier Barcons. The programme included visits to the Extremely Large Telescope (ELT) and the Very Large Telescope (VLT). The delegation learned about the construction progress of the ELT, which will be the largest optical telescope in the world. The tour offered a chance to see some of the science in action and check out the European instruments and key technologies at work. The Leibniz Institute for Astrophysics Potsdam (AIP) was deeply involved in developing such technologies and will continue to play a key role in the future. The AIP is making significant contributions in the field of instrumentation for the Extremely Large Telescope (ELT) and is, for example, involved in the development of the ANDES spectrograph and MOSAIC.
Another major project that shows AIP’s commitment is 4-metre Multi-Object Spectroscopic Telescope (4MOST), one of the biggest ground-based survey instruments in Europe, which was built under the leadership of the AIP. On 18 October 2025, 4MOST captured its first light from the night sky at the European Southern Observatory's (ESO) VISTA telescope, also located at the Paranal Observatory. 4MOST will investigate the formation and evolution of stars and planets, the Milky Way and other galaxies, and the universe as a whole. The instrument can simultaneously break down the light from up to 2400 celestial objects up to 18,000 colour components, enabling astronomers to analyse their chemical composition and physical properties in detail.
In her address, Minister Bär emphasised the need to protect the natural heritage, such as the dark and quiet skies, as they inspire the younger generations in their curiosity for STEM research. She highlighted the importance of ground-based astronomy, its synergies with space research and the significance of developing and investing in both fields, as they drive technology in Germany and the whole of Europe.
“Thanks to the AIP’s contributions to the instrumentation of ESO telescopes, we are enabling students and PhD candidates in astrophysics to participate in the analysis of the latest data from the world’s most advanced telescopes,” says Matthias Steinmetz.
The visit underlines the importance of close international cooperation in astronomical research and the key role of the AIP in linking scientific analysis, instrument development and data infrastructure in the European research environment.

You can combine search terms with and, or and/or not, e.g. Philo not logy.
You can use brackets to separate combinations from each other, e.g. (Philo not logy) or (Psycho and logy).
Coherent groups of words will be located as complete phrases if you put them into quotation marks, e.g. “Federal Republic of Germany”.
You can also use the advanced search without entering search terms. It will then follow the criteria you have selected (e.g. country or subject area).
If you have not selected any criteria in a given category, the entire category will be searched (e.g. all subject areas or all countries).
