CALADRI is a speculative research project where astrophysics and fiction converge. Rooted in real scientific data, it imagines a slowly rotating exoplanet where life can survive only within a migrating twilight belt between scorching light and frozen darkness. Within this fragile zone, two societies move in constant adaptation — preserving their knowledge in underground echo chambers that archive climate rhythms and celestial signals to transmit memory across deep time.
Through sound, video mapping, and narrative fragments, po:era invites visitors to enter an immersive field of perception — part planetarium, part performance.
From dusk onward, the Historic Auditorium transforms into a participatory environment where audiences are invited to listen, speculate, and join worldbuilding sessions exploring coexistence between science and fiction.

In parallel Po:era hosts the fourth edition of the site-specific art festival ONSITE which explores the speculative futures of three cultural sites in Berlin: a museum, cinema, and theatre. Po:era’s world-building project CALADRI - developed as part of their research of Anatomia Publica - will kick off the festival program on 6 November at Tieranatomisches Theater.

During opening hours (14:00–21:00), visitors are invited to explore the Tieranatomisches Theater as a landscape of observation and imagination.
Marcela Moraga’s research station can be experienced in the Rotunda (ground floor), while po:era’s immersive installation activates from dusk (18:00–21:00) in the Historic Auditorium and Library (first floor).
All spaces are barrier-free and wheelchair accessible.
Information about the artistic research projects is available in German and English.
Please note that the immersive experience CALADRI by po:era is presented in English only, and the Artist Talks are held in English due to the international composition of the guests and audience of Berlin Science Week.
The installations can be experienced independently throughout the week, with moments of artist and curator presence announced in the daily programme below.

Constanze Gülle – Rumstreunern: Dog Training, Behavioural Counselling and Dog Walking in Berlin

Constanze Gülle is a dog trainer, dog walker and educator. Having grown up in the countryside, she has been surrounded by dogs since childhood – as social companions, learning partners and personalities with their own expressions. With Rumstreunern, she offers dog training, behavioural counselling and dog walking in Berlin, promoting a harmonious and respectful coexistence between humans and dogs. Today, she leads dog groups through Berlin’s Grunewald forest with calmness, respect and attentiveness. In her work, she combines pedagogical experience with a mindful, queer perspective on human–animal relationships, creating spaces in which dogs and their humans can perceive and learn from one another.
