The planetarium is housed within a 10-meter diameter dome utilizing a 16K resolution projection system.
The centre is situated on the edge of the South Downs, Britain's newest national park at the time of its designation.
The facility was formerly known as INTECH Science Centre before rebranding.
The structure's architecture incorporates energy-efficient design principles intended to minimize its carbon footprint within the park.
The interactive exhibits are constructed to be modular, allowing for regular updates to reflect current scientific research.
The centre runs a dedicated 'Science Communicator' program to train staff in translating complex technical concepts for younger audiences.
The Winchester Science Centre & Planetarium features the UK's largest standalone planetarium, which uses a high-definition digital projection system. The facility is a hands-on, interactive science and technology centre located within the South Downs National Park. Permanent exhibits focus on physical science, engineering, and space exploration, designed primarily for primary school-aged children. The centre operates as an educational charity aimed at promoting STEM subjects through experiential learning. Key interactive zones include a simulated mission control and explorations of sound, light, and movement. The building itself is noted for its distinctive, iconic blue-domed roof that houses the planetarium. Outdoor areas include a nature trail that highlights local ecological diversity within the park boundaries. The venue regularly hosts live science demonstrations and workshops aligned with the UK national curriculum.
