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.
