Product Description:

Celestia is a free real-time space simulation that lets you experience our universe in three dimensions. 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 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.

I've got a 1.67 GHz PowerBook G4 with 1GB of RAM running 10.4.3. Both this version, and 1.4 before it take all the CPU I've got and runs it into the ground. And that's simply by launching it and anytime it's idle. It is really snappy when I move around the galaxy but really, it should take a much larger break when I am not doing anything in the application. I even tried the new OpenGL option you suggested with no change in CPU during "idle" times.

Sorry, as slick as this seems to be I can't just let my processor cook simply because I forget to quit the application.

In the future it would also be nice to have an on-line version of the changelog -- I couldn't find anything like it at the celestia.sourceforge.net site. And an 18MB download just to find out the latest changes in the 48KB changelog is a lot of wasted bandwidth for everyone's network: mine, the software mirror sites and everything in between.

Hi, I'm one of the devs for the OS X version of Celestia - one of the major changes in this version is that the app is now Universal (runs on Intel and PowerPC Macs). Celestia should also run correctly on versions of OS X earlier than 10.3.9. Tiger 10.4.3+ users with good graphics cards should definitely check out the new OpenGL 2.0 render path (Ctrl+V) in Celestia 1.4.1!
