Stellarium/stellarium
Stellarium
Stellarium is an open-source 3D planetarium simulator and cross-platform sky map used for astronomical observation and study. It provides a real-time simulation of the night sky that renders astronomical objects and atmospheric conditions using OpenGL.
The software functions as a visualization tool to show how stars and planets appear through optical instruments. It allows users to identify celestial objects from any location on Earth, simulate stargazing site visibility, and plan targets for observation with binoculars or telescopes.
The system incorporates an atmospheric scattering model, coordinate-transformation pipelines, and catalogue-driven object mapping to project a three-dimensional model of the universe. It is available as a desktop application for Linux, Windows, and macOS.
