Staring July 2nd, a new exhibition will be on display at the Old Observatory: More-than-Planet. This exhibition focuses on the following question: how do we imagine our planet?

Explore this question from a unique perspective at More-than-Planet. Consider the factors that shape our (space-based) views on environmental pressure and conflict by immersing yourself within the artworks of five cutting-edge international artists.  These transdisciplinary artworks using space-based technologies open a dialogue surrounding humanity’s next chapter in its delicate relationship with Earth.

Learn more about the works and their artists.

More-than-Planet is produced by the Waag Society and Old Observatory. More-than-Planet Exhibition is part of the Leiden 2022: European City of Science programme and a side event of the European Open Science Forum. The exhibition is open from the 2nd of July until the 23rd of December.

Starting July 2, the Old Observatory Visitor Center will be open to the public at the following times:

Monday closed
Tuesday - Friday 13:00-17:00
Saturday - Sunday 11:00-17:00

In addition to the exhibition, you can also take a guided tour from an astronomy student. In one hour, the student will tell you more about the exhibition and you will be taken to one of our historic telescopes. Please note: because these tours are during the day, it will not be possible to look through a telescope during the walk-in tours.

A maximum of 15 people can participate in a tour. To be sure of a spot, we recommend reserving a time slot. Ticket sales at the Observatory box office are available as long as there is availability.
