Sep 30, 2009 Celestia is a real-time visual space simulation astronomy program. It is a cross platform, open source software and released under the GNU General Public License. NASA and ESA have used Celestia in their educational and for interfacing to trajectory analysis software. It allows users to travel through an extensive universe, modeled after reality, at any speed, in any direction and at any time.
Welcome to Celestia
... The free space simulation that lets you explore our universe in three dimensions. Celestia runs on Windows, Linux, and Mac OS X.
Unlike most planetarium software, Celestia doesn't confine you to the surface of the Earth. You can travel throughout the solar system, to any of over 100,000 stars, or even beyond the galaxy.
All movement in Celestia is seamless, the exponential zoom feature lets you explore space across a huge range of scales, from galaxy clusters down to spacecraft only a few meters across. A 'point-and-goto' interface makes it simple to navigate through the universe to the object you want to visit.
Celestia is expandable. Celestia comes with a large catalog of stars, galaxies, planets, moons, asteroids, comets, and spacecraft. If that's not enough, you can download dozens of easy to install add-ons with more objects.

- Celestia is arguably the greatest program for Mac OS X, at least for science-lovers. However, it's hard to find and install the most recent version. First, Celestia's homepage does not give the most current version of Celestia for Mac OS X - only version 1.3.1 is listed, when in fact version 1.3.2 is already available on their SourceForge files page.

The program, based on the Hipparcos Catalogue, allows user to display objects ranging in scale from artificial satellites to entire galaxies in three dimensions using OpenGL. Unlike most planetarium software, the user is free to travel.

Introduction[edit]
Celestia uses OpenGL graphics routines to draw its pictures of the universe. Unlike DirectX, which is available only on computers running Windows, OpenGL graphics libraries are available for many different types of operating systems.OpenGL was originally developed by SGI but now is available for use on almost all computers and graphics hardware. The OpenGL WikiBook has more details.
Celestia can run on most computers, but to see all of its 'eye candy' a modern graphics card implementing OpenGL v2.0 is essential. Even when the best available graphic cards have been installed, some computers have problems running Celestia because their graphics drivers are out of date or buggy. Regularly check the Web site of the manufacturer of your computer or of your graphics card to make sure you have the current driver version. Updated drivers are provided often.

Operating System Limitations[edit]
Many computer and O/S limitations are described in Celestia's list of Frequently Asked Questions.
Linux[edit]
- OpenGL is distributed in many Linux flavors since is open source, but the graphic drivers not always are open source, thus, aren't included in all Linux distros.
Mac OS X[edit]
- Graphics driver updates for Mac OS X are available in updates to Mac OS X itself, not in general as separate driver updates by NVIDIA or ATI. This means 'upgrade your driver' on OS X means 'make sure your version of OS X is up-to-date'. You may have to spend money in order to get the current version of OS X.
- Point sprite primitives do not work on versions of OS X earlier than 10.4.
- Point sprites are not supported properly on Tiger (PPC and Intel architectures). Colors may appear incorrect, and hard freezes requiring a reset have been seen. VBO seems to be involved. Apple has been made aware that this is almost certainly a driver bug, but no fixes have been promised. Behavior on Leopard is unknown.
- The OpenGL 2.0 render path is only supported on Tiger 10.4.3 or later, regardless of the graphics card.
Holes may appear in orbit paths on certain ATI configs. A workaround is being investigated.Fixed in 1.5.0.
Windows[edit]
- The graphics drivers provided with your brand new computer hardware already are obsolete. Usually several months have passed between the time its software was configured and it was provided to you. Be sure to download and install the most recent graphics drivers provided on the Web site of the manufacturer of your computer's graphics hardware.
- Windows XP includes a software-only OpenGL library. It's used on systems without 3D hardware or when hardware acceleration is disabled in the Display Control Panel. It implements only OpenGL v1.1, Celestia's Basic rendering path, so it has limited functionality and runs rather slowly, but it is relatively bug-free.
- Celestia does not use DirectX, which is Microsoft's proprietary 3D graphics programming library. Unfortunately, whenever Microsoft's DirectX libraries are updated, the manufacturer's OpenGL drivers are replaced by obsolete versions provided by Microsoft. Whenever you update DirectX, be sure to reinstall the graphics drivers using the most recent versions provided by the manufacturer of your computer's graphics hardware.
