Open House Day: Behind the Scenes at ESO on 3 October 2024

25 September 2024

On Thursday 3 October 2024, the European Southern Observatory (ESO) will open its doors during the Open House Day of the Garching Research Campus in the north of Munich, Germany. This will be an exciting opportunity to visit ESO and other renowned research institutes for a behind the scenes experience, all for free. The ESO Supernova Planetarium & Visitor Centre will also offer planetarium shows and other activities.

From 10:00 to 17:00 CEST, the ESO headquarters in Garching bei München will open its doors to everyone who is curious about space and astronomy. Discover the science and technology behind ESO’s state-of-the-art telescopes, meet the people working on and with them, and find out how instruments are prototyped and tested. ESO astronomers and engineers are at the premises all day to answer your questions. ESO will even provide a live connection to Chile, where the organisation’s telescopes are hosted. In short: a perfect Science Day Out!
