Visitor centre

Chalmers is building a new visitor center at Onsala Space Observatory. Here, schoolkids and the public will be able to get close to astronomy, Earth sciences and space technology. Located close to the telescopes at Onsala Space Observatory, the centre will be the result of an innovative and climate-friendly building project. Construction is to start in spring 2021.


At the visitor centre, school classes and the general public will be able to experience and discover how technology makes it possible to explore space and the universe. The centre will allow visitors to get close to Onsala Space Observatory's telescopes and instruments, the research they conduct, and the observatory's international projects, in particular the SKA. It will also showcase the space research being done at Chalmers and by its partners in west Sweden.


A new, modern exhibition is being created in the visitor center. Here, we want visitors of all ages to be able to discover the universe, our planet the Earth, and the technology we use to explore our place in the cosmos.

Visitors and how to visit

The visitor center will only be open for prebooked groups and events. Visits are primarily aimed at school students from year 2 up to upper secondary school, and to the general public. We will offer guided tours to schools and other groups, plus regular events for the general public.


The new building is located close to telescope at Onsala Space Observatory. The building is close to the 25-meter telescope and to Onsala's Twin Telescopes, on the site of the previous exhibition building.

Sustainable construction

The building will be built following new, sustainable routines. As far as possible, climate impact is minimized and reuse and circularity is maximized. The construction project will break new ground in terms of sustainability. Before and during construction, we are testing many new approaches, from emissions-driven procurement to the design and implementation of new and redevelopment projects with minimal climate impact.

Chalmersfastigheter is purchaser and developer for the project. The building has been designed by White arkitekter. NCC Building Sweden is the building contractor for the project.

Time plan

Construction is expected to continue in 2021. The building will be ready for the first visitors in 2022. 


Planning and construction are coordinated by the Department of Space, Earth and Environment at Chalmers and Chalmersfastigheter. Onsala Space Observatory works together with Chalmers fundraising office, Universeum, Slottsskogsobservatoriet, and others.
