Celestia - Space Simulator
Celestia Space Simulator lets you move between celestial objects and observe them from different locations and times.
Choose it to explore a three-dimensional catalog rather than identify a single point in tonight's sky.
You can move the viewpoint to another world, change simulation time and extend the catalog with add-ons.
Keep in mind: Add-on accuracy and scope can vary; it is not a substitute for calibrated observing equipment.
