OpenSpace is open-source software for interactive astrovisualization. It renders the universe at scales from spacecraft instruments to galactic structure, using data from NASA, ESA, and scientific institutions around the world. Built for planetarium domes, museum exhibits, classrooms, and any computer that can run modern graphics, OpenSpace lets users navigate continuously from Earth’s surface out to the edge of the observable universe, with the data presented in precise context of the observable universe. The software is free, cross-platform (Windows, Linux), and developed openly on GitHub.

Our mission

OpenSpace exists to make the universe accessible. The vast majority of what humans have learned about space lives in research papers, mission databases, and specialist tools that most people never see. We believe that data this important shouldn’t require a PhD to explore. By giving museums, planetariums, teachers, and citizens the same visualization capabilities that researchers use, OpenSpace turns the universe into something anyone can navigate.

The project also serves the research community itself. Scientists use OpenSpace to communicate findings, explore their data in relation to other relevant datasets, and collaborate across institutions.
