After 20 years of development, the Stellarium 1.0 project was released, developing a free planetarium for three-dimensional navigation through the starry sky. The basic catalog of celestial objects contains more than 600 thousand stars and 80 thousand deep sky objects (additional catalogs cover more than 177 million stars and more than a million deep sky objects), and also includes information about constellations and nebulae. The project code is written in C++ using the Qt framework and distributed under the GPLv2 license. Builds are available for Linux, Windows, and macOS.
The interface provides flexible scaling, 3D visualization and simulation of various objects. Projection onto the dome of the planetarium, creation of mirror projections and integration with the telescope are supported. Plugins can be used to extend the functionality and control of the telescope. It is possible to add your own space objects, simulate artificial satellites and implement your own forms of visualization.
In the new version, the transition to the Qt6 framework has been made and an acceptable level of accuracy in reproducing past states has been provided. A new significantly improved sky illumination model is proposed. Improved detail when simulating eclipses. Expanded capabilities of the astronomical calculator. Improved performance on screens with high pixel density (HiDPI). Improved dithering. Added information about the perception of objects of the starry sky in the culture of the peoples of the Samoa archipelago.
