At the Archenhold-Sternwarte on 14 June 2025

"Everything is relative" – On June 14th, from 2 p.m. to 1 a.m., the Archenhold Observatory will be transformed into a galactic festival grounds: We're celebrating Albert Einstein's revolutionary ideas and invite young and old to the Cosmic Summer Festival: Einstein Edition.



Look forward to 360° insights into the program of the Zeiss Small Planetarium, fascinating celestial observations with the Cassegrain telescope and in the Solar Physics Cabinet, as well as exciting lectures in the legendary Einstein Hall. Visit the world's longest movable refractor telescope on the roof of the observatory – a real highlight!


Outside, you'll find an illuminated planetary path, water and air rocket launches, hands-on stations for children, music, and a relaxed atmosphere. Culinary refreshments will, of course, be provided.

Celebrate Einstein's Legacy


To mark the 110th anniversary of Albert Einstein's lecture on General Relativity, this year's events in and around the museums are under the motto "Everything is relative."


Almost 110 years ago, Albert Einstein gave his first public insight into his General Theory of Relativity in the Great Hall of the Archenhold Observatory in Berlin-Treptow, creating a milestone for human knowledge. His groundbreaking ideas, which he presented on June 2, 1915, in Germany's largest and oldest public observatory, not only shape science to this day, but also inspire lifelong learning and research.
