نرم افزاری متن باز برای کامپیوتر شما
با استفاده از این نرم افزار می توانید آسمان بالای سر خود را به صورت سه بعدی و در زمان حقیقی بر روی دسکتاپ خود داشته باشید.
این نرم افزار می تواند ستاره ها ، سیارات ، صورت فلکی و ... را نمایش دهد.
ضمن آنکه این نرم افزار را می توانید بر روی پلتفرم های مختلفی مانند لینوکس ، ویندوز و مکینتاش نصب کنید و از آن استفاده کنید.

Stellarium is a free open source planetarium for your computer. Stellarium renders 3D photo-realistic skies in real time with OpenGL. It shows a realistic sky in 3D, just like what you see with the naked eye, binoculars or a telescope. Stellarium displays stars, constellations, planets, nebulas and others things like ground, landscape, atmosphere, etc. It is available for Linux/Unix, Windows and MacOSX. It is being used in planetarium projectors. Just set your coordinates and go.

• default catalogue of over 600,000 stars
• extra catalogues with more than 210 million stars
• asterisms and illustrations of the constellations
• constellations for eleven different cultures
• images of nebulae (full Messier catalogue)
• realistic Milky Way
• very realistic atmosphere, sunrise and sunset
• the planets and their satellites
• a powerful zoom
• time control
• multilingual interface
• fisheye projection for planetarium domes
• spheric mirror projection for your own low-cost dome
• all new graphical interface and extensive keyboard control
• telescope control
• equatorial and azimuthal grids
• star twinkling
• shooting stars
• eclipse simulation
• skinnable landscapes, now with spheric panorama projection
• add your own deep sky objects, landscapes, constellation images, scripts...

Changes in Stellarium 0.10.3 [2010-01-28]:
- Based on Qt 4.6.x
- Bundling of plugins: Satellites, Oculars, AngleMeasure, CompassMarks, TelescopeControl, TextUserInterface.
- New script engine improvements including variable script running speed, and a script console (activate with F12).
- Made tabs in GUI smaller by moving titles under the icons.
- Updated the plugin API to allow to compilation and easy distribution of static plugins.
- Added plugins window.
- Got rid of the boost library dependency.
- The whole sky display viewport is now contained in a class deriving from QGraphicsWidget, allowing to move and resize it as a normal widget.
- Generalized the use of shared pointers for StelObject management.
- Use vertex shaders for computation of atmosphere color if OpenGL supports it.
- Optimized openGL calls by replacing glBegin()/glEnd() by the use of vertexArray.
- Optimization of critical parts of the projection code.
- Added code for managing and displaying non-convex polygons + unit tests.
- Recoded the StelGrid code to support non ponctual sky regions, and optimized API (new class StelSphericalIndex + unit tests)
- Optimized many part of the code by reducing creation of temporary Vec3d/Vec3f.
- Optimized JSON parser (x25 speed improvement) + unit tests.
- Migrated all text drawing system to QFont. This fixes long standing bugs for displaying arabic and asian characters in the sky. Also allow to get rid of 6 source files and of the freetype dependency (managed internally to Qt)
- Switch default back end mode to native for Windows as ATI drivers often have problems, still raster default for other platforms.
- Add graphics-system option.
- Fixed magnitude computation for most of the planets.
- Use GL Shader for stars rendering if OpenGL >= 2.1.
- Re-organized the startup by moving log and command line processing to main.cpp.
- Re-coded all the management of extra star catalogs.
- Implemented partial support of OpenGLES 2.0.
- Moved official plugins code into plugins/ and changed the cmake config so that they are automatically compiled in static.
- Re-coded the texture engine based on Qt loading features (Got rid of explicit libjpeg and libpng dependencies!).
- Allowed to first render the sky in a frame buffer.
- Moved the code related to viewport distortions into a new class StelViewportEffect based on frame buffer object.
- Added working cmake targets for compilig and runing unit tests.
- Added a delay before making Simbad name lookup queries to avoid sending too many requests.
- Added the Aztec sky culture.
- Many minor fixes and optimizations.
