Description:

Celestia is a free real-time space simulation that lets you experience
our universe in three dimensions. Unlike most planetarium software,
Celestia does not 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 travel 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. Many add-ons and vastly improved textures of high
resolution are available for Celestia.

16 years ago

* Improved inclusion of light travel delay, also in KDE time setting dialog
* Fixed lookback command for subsequent changes of target speed
* Allow wildcard character * inplace of extension for texture filenames
* Fix bump mapping (again)
* Use standard normal maps instead of x-reversed ones
* Compute the radii of stars more accurately by using bolometric magnitudes
* Permit star names to be defined within .stc files
* Fixed near clipping of small deep sky objects
* Windows: added auto magnitude toggle to render menu
* KDE: added popup error notifications
* Allow oblate planets to have atmospheres
* Corrected specular highlights; abrupt cutoff near terminator eliminated
* Fixed 'hole in the sky' bug
* Allow sunset color to be specified in .ssc files
* Improved rendering of objects in daytime skies
* Bound Ctrl+P to mark/unmark selection
* Implemented tab completion of star, planet, and deep sky object names
* Implemented new, scientifically accurate Pluto-Charon textures
* Windows: bound Ctrl+C to copy cel:// URL to clipboard
* Modified the way field of view works: compute the field of view based
on distance to screen, monitor resolution, and view size; don't attempt
to maintain a constant vertical FOV when splitting views.
* Implemented alternate surfaces for planets
* Added overlay textures that are applied on top of other surface maps
* Bound + to toggle limit of knowledge maps
* Improved estimates for stellar rotation period; previously all stars
were assigned the same rotation rate as the sun.
* Added locations--labels of planetary surface features
* Bound & to toggle display of location labels
* Added a locations dialog for controlling the display of locations
* Allow orbit paths to be turned on independently for all object classes
* Added a 'scaled disc' style for rendering stars
* Bound shift+arrow keys to orbit reference object
* Added unmarkall command for scripting
* Added missing render flags for script commands: automag, atmospheres, grid
* Added a MeshCenter field for properly position and rotation of 3DS meshes
* Implemented virtual textures, for ultra-high resolution texture mapping of
planets.
* Added textures for Hyperion and Proteus
* Made cancel script command stop motion, tracking, and any object-relative
coordinate system.
* Adjusted estimates for radii and rotation periods of extrasolar planets;
rotation rates account (somewhat) for the effects of tidal despinning.
* Fixed a bug that was causing precision loss in orientation values; this fixes
some of the jerkiness apparent at very low fields of view.
* Corrected radii of Uranus's rings
* Added ring system for Neptune
* Corrected errors in Callisto's orbit
* Modify the right-drag rotation rate based on the distance between the
camera and the selection.
* Made ambient light work for bump mapped objects in the vertex program/DOT3
render path.
* Bound Shift+C to center/orbit. This places the selection in middle of
the view while keeping the reference object at the same point in the view.
* Added locations-labels of all world capitals (240) with importance
weights calculated from their numbers of inhabitants
* Added solar system location labels

Is there any KStars bridge or integration?

I mean, it could benefit both programs to do "advertising" in each other.

So people interested in Astronomy on Linux can have a quick overlook at all impressive free softwares that exist in that domain. What impress me the most with KStar and Celestia is how far they go, where Windows commercial counterparts are expenssive and ininteresting...

I knew KStars for some years, but just discovered Celestia today. And it seams to be of the same polishment, with the same spirit.

this program is one of the opensource programs which really impressed me!

is there a chance to have a screensaver built on this? there is qstars, but i don't like it that much..

Guys this program is amazing. I am speechless. Thanks!! I still havent played around enough but I assume you can load custom textures for the planets.

hello,

ESA seems to use celestia to show mars express orbit insertion:
