Stellarium is an open-source desktop planetarium program developed by the Stellarium team that renders the night sky in 3D with the same fidelity as naked-eye, binocular, or telescope observation. Designed for astronomy education, outreach, and hobbyist stargazing, the software calculates and displays the positions of more than 600,000 stars, the Sun, the Moon, planets, nebulae, and the Milky Way in real time; users can set any date, time, and terrestrial location to preview sky maps for planning observation sessions, controlling motorized mounts, or creating content for presentations and astrophotography. The application belongs to the Science / Astronomy category and is frequently installed by educators running classroom demonstrations, researchers verifying celestial coordinates, and hobbyists who want an interactive star chart that reacts to mouse movements and keyboard shortcuts. Version 26.1, released as the forty-sixth public build in a lineage that spans forty-five earlier iterations, continues a development trajectory that has added telescope control plugins, fisheye projection for domes, and extensive star catalogues since the project’s inception. The cross-platform codebase is maintained under the GPL license, ensuring transparency and community contributions that refine accuracy, performance, and localization. Stellarium is available for free on get.nero.com, with downloads provided via trusted Windows package sources such as winget, always delivering the latest version and supporting batch installation of multiple applications.
