Long Night of the Sciences

June 28, 2025

• 

On the "smartest night of the year", numerous scientific institutions and laboratories open their doors and invite visitors to participate.

Once a year, numerous scientific institutions in Berlin and Potsdam invite visitors to laboratories, archives, libraries and lecture halls that are otherwise not open to the public. From 5 PM until midnight, visitors can participate in exciting experiments, learn about current research results and enjoy stimulating conversations.

Where Scientists and Citizens Exchange Ideas

These personal encounters, coupled with the insight into places that are often "hidden" from the public and the night-time event character, make this event particularly attractive. Around 27,000 visitors took advantage of this opportunity last year. But it's not just the guests who can learn a lot at a Science Night. The direct dialog also has an inspiring effect on the scientists. That's why there are more and more discussion formats and opportunities to participate in the extensive Long Night program. Around 1,500 individual events are on offer, including more than 800 specially designed for children and young people.

Long Night of the Sciences Promotes Real Research

As every year, the Long Night of the Sciences 2025 takes a stand against misrepresentations, invented truths and irrationalism with the guiding principle: science as the answer to fake news, conspiracy theories and fatal errors.

Shuttle bus service at the Long Night of the Sciences

Most of the participating institutions are easy to reach by public transport. Special bus routes have been set up for travel to some venues, which can be viewed on the organizer's website (see below).
