فراد بسياري به آسمان و نجوم و سيارات علاقه دارند. اين بار مي خواهيم به معرفي نرم افزاري جالب در اين زمينه بپردازيم كه داراي كاربرد هاي فراواني است. نرم افزار stellarium يك نرم افزار با سورس باز و كاملاً رايگان در مورد نجوم است. اين نرم افزار داراي محيطي زيبا و كاربر پسند است. توسط اين نرم افزار مي توان به آسمان ، سيارات ، مدارات و … دسترسي داشت.
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.
Key features of "Stellarium
· Over 120000 stars from the Hipparcos Catalogue with name and infos for the brightest ones.
· Planets and major satellites in real time (position computation now accurate enough for eclipse or transit simulation).
· Drawing of the 88 constellations with their names.
· Mythological figures of the 88 constellations.
· Textured displaying of more than 70 nebulas (Orion, M31 etc..).
· Photo-realistic Milky Way.
· Star twinkling.
· Shooting Stars.
· Skinable landscape (ground, fog, mapping of fisheye pictures).
· Ultra fast realistic atmosphere rendering (Sunsets, sunrises etc...).
· Automatic eye adaptation to sky luminance using physiologic model.
· Grids in Equatorial and Azimuthal coordinates.
· Equator and ecliptic coordinates lines.
· Smooth real time intuitive navigation.
· Powerfull zoom to see planet and nebula like in a telescope.
· Equatorial and altazimutal mount mode.
· Standard perspective and wide angle (fisheye) projections modes (e.g for planetarium dome).
· Time control (real time and accelered time modes).
· Graphical menu for simple utilisation.
· Clikable stars, planets and nebulas with informations.
· Windowed and fullscreen modes.
· Full dome (180°) projection mode for planetariums.
· Text user interface for planetariums.
Changes in Stellarium Stellarium 0.9.0
This new release brings a lot of new features such as a (much) larger star catalog, more landscapes, constellation culture and art, asteroids and many others.
- Larger star catalog including stars from Hiparcos, Tycho2 and NOMAD
- Can select multiple constellations at one time
- Local script directory is reread when enter TUI
- Inuit constellation art by Johan Meuris
- More sky cultures
- Large code reorganization into a modular structure based on StelModule, StelApp singleton and its "manager" classes providing services to the modules.
- Projection code cleaned and splitted into Mapping classes.
- Movement control code encapsulated into the MovementMgr module.
- Code cleaning and commenting.
- Sidereal day/week keystrokes (ALT -, ALT =, ALT [, ALT ]).
- Data files reorganized
- Added back Hawaiian translations (invented locale "hw")
- Orthographic projection, Lamberts Equal Area projection, Cylinder projection.
- Interpolate the elliptic coordinates (or the spherical coordinates in case of the moon).
- Do not place the Earth at the EMB but at its proper position.
- New orbit type comet_orbit for proper calculation of elliptic, parabolic, hyperbolic orbits.
- Added loading of jpeg textures and re-coded most of the texture manager.
- Allow loading of plug-ins (unstable until version 1.0).
- Selection of object is managed per module, and by the StelObjectManager.
- Recoded Grid display to allow for adaptative scale wrt zoom and labeling.
- The main window managed by QT4.2 instead of SDL.
- Window resizing
- Smooth go to selected solar system body by pressing control-g
- Location map updates on changing observer to new solar system body
- Titlebar updates after moving to new planet
- Landscapes may now have location, can update observer by selecting landscape
- More nebula textures and better placement of most existing textures
- Build is now managed by cmake instead of autoconf/automake. These old tools are still supported for this version.
