This is a really fun program. I've had it on my hard drive for a long time. My only issue is how it totally pins my G4 CPU whenever it runs, more than any other app does.
I've been using this on linux for quite some time and it is a great application.. along the same lines, does anyone know of any good software for Macs to use my DSLR with a celestron scope?
Also on an astrological track, Stellarium is open source software for displaying the Earth's sky. No cosmic voyages, but it does draw constellations just beautifully.
Whoops. I was thinking about the constellations and got my adjectives confused. My horoscope said it there might be some embarassing moments this month.
Freezes my OSX 10.4.3 machine 5 seconds after launch, everytime. Seems like it is starting to work, then my clock stops ticking, then mouse stays alive for about 15 seconds, then total freeze up. My machine is expertly maintained, and tight.
I had the same problem on my G4 1.25 GHz running 10.3.9 (and my system is obsessively clean too). The readme file contains a troubleshooting section with the suggestion to remove the '#' before a certain line in the config file (I won't pretend to undestand the programming technicalities behind this)..I followed these instructions and the program now runs perfectly for me.
This comes from some ATI graphic cards not understanding a specific OpenGL extension. If you uncomment that line, you disable the use of that extension (for a small performance penalty) and it works.
Remember, the more powerful your video card, the better. It will work better on a NVidia card since the developers are on NVidia.
While it's true that the lead developer is employed at NVIDIA, on the Mac the situation is a bit different and some NVIDIA-specific render paths don't work even on NV30+ cards. And while it's true that very recent cards are obviously much better for Celestia use, the crashing bug is due to a very specific bug in the driver for the ATI Radeon 9000/9200 cards and has nothing to do with your video card being too old; for example ATI Rage cards don't lock up. In fact, recent video cards still cannot perform OpenGL 2.0 rendering correctly on OS X while on Windows it's beautiful *sigh*

Thanks for the hint. I took out the # on the 'ignoreGLE' line and it works ok for me as well.

I also have encountered the big freeze, everytime. Freezes my entire Mac so I have to reboot - I can't roam the universe, but have to re-boot. Re-moved the app from my Mac.
I am running on a Dual G4 Tower, 1 GHz, OSX 10.3.9, with 1.75 Gb of RAM. I don't think this app is quite ready for prime time... --- Tombert
Hi, I'm a developer for Celestia. The lockup, as mentioned by other posters, is caused by a bug in the drivers for a small subset of graphics cards and has a known workaround. Yes, it is Apple's and ATI's fault, not Celestia's. I've tried lobbying Apple but apparently they have either found the bug not worth fixing or don't know how.

When I go to the International Space Station (ISS) in Celestia, the Earth rendering looks really bad. I know there are ways to fix this by downloading higher resolution Earth textures but I have no idea how to go about doing this in Celestia. Has anyone done this (in particular the blue marble NASA textures)?
To get more textures (greater resolution, night, clouds, etc) you can go to the Celestia Motherlode site as pointed in the original posting. Plenty of textures, 3D models, ships (some are truly amazing), even whole systems lies there. Some files are purely fantasy while others are based on newly discovered celestial bodies and stuff and are made by very serious people.

I installed the 2001 'discovery' package. Any idea how to find the ship? Kcncrew pack for mac os x. I _think_ I did everything right..
Oh, I forgot. To get the earth to show 'nicely' when viewed from ISS, you'll have to put an amazingly high texture on the earth that will probably put your Mac to a crawl. These textures exists put you have been warned :)
But, by all means, feel free to experiment. ;)
Yeah it would be cool to see this in action. :)
If you are interested in doing more astronomy and less pretty picture gazing (not that there's anything wrong with that), check out XEphem. It is a serious astronomy program that probably does more than most people need, but it has lots of neat tools for the professional or amateur astronomer. You can certainly build your own copy or download a binary.
Celestia Mac Os X
The version at Apple's Downloads is a bit older than the current version, but if you're not into compiling your own or using Fink, you'll be stuck a bit behind the times (not that most people will notice)!
Of particular interest to developers is the fact that Apple used the Celestia application as a demo of performance enhancement techniques. The following page provides links to a modified version of Celestia and discusses how its performance was improved by using Apple's free analysis utility 'Shark':

Hi, I'm a developer for Celestia. Great to see Celestia mentioned here. Note that for the record, Celestia is not a Java program - it has a C++ platform-independent core, with an Objective-C Cocoa GUI for the Mac. Anyway, Celestia is getting a lot of changes lately so visit http://www.shatters.net/forum/ often for new versions. We hope you enjoy this great program!
