Celestia is a free real-time space simulation that lets you visually experience|
our universe in three dimensions. Celestia was the initial inspiration and
creation of Mr. Chris Laurel, a Seattle, WA computer programmer who in 2001,
decided to write a free software program to be made available to everyone on
the world-wide-web that would place you in control of a virtual reality world
of the Solar System. His vision and dedication gave birth to a program that is
unlike any other space simulation program in existence. Celestia doesn't
confine you to the surface of the Earth as many other programs do. Instead,
Chris created a dynamic capability to travel throughout the Solar System and
anywhere else in space, at any speed, at any moment of time and in any
direction you choose. If you wish, you can fly via your own "hyperdrive"
spacecraft to visit stars within the spiral arms of the Milky Way beyond the
confines of our Sun. You can even travel completely out of the Milky Way
galaxy and view it from deep space.
