Package: wnpp Severity: wishlist This thing is simply cool. Superb graphics, superb program design. Beats similar programs without even thinking about it. I was kinda surprised not to find an ITP for this already.
Celestia is a real-time visual simulation of space in our local region of the universe. Choose a point within about 1000 light years of Earth, and Celestia will show you an approximation of how it would appear to your eyes were you actually there. Some of what Celestia shows is necessarily hypothetical--the farther away from Earth you get, the less real data there is and the more guesswork is involved. Thus Celestia supplements observational data with good guesses based on models of stellar and planetary processes. License: Celestia itself is GPL and the object database, Hipparcos, is, IIRC, public domain. Will check on that. URL: http://celestia.sourceforge.net/
