Stellarium是一个免费开源的桌面虚拟天文馆软件,可在Linux/Unix, Windows and MacOSX平台上运行.它使用OpenGL对星空进行实时渲染,在你的电脑桌面上生成一片虚拟3D天空,因此星空效果和你用肉眼,望远镜或者天文望远镜 观察到的星空别无二致.Stellarium也有白天和黑夜变化,你可以通过调整日期或时间,来看到不同季节的天空.下载:Stellarium 0.10.1

Stellarium 0.10.1 will be released in the coming days: it is the best time to update and finalize translation of the program in your language. Have a look in https://translations.launchpad.net/stellarium/0.10 to see if the translation is complete for your language!
If you want to be more involved, you should also join the stellarium-translation team: https://launchpad.net/~stellarium-translation and subscribe to the matching mailing list to be kept up to date.
