Perhaps in order to add more realism to the stars in Celestia, you could implement star lifespans, including different ways their "lives" could commence and end. I already know that experimentations on protoplanetary disks and protostars exist, and even nebulae that include different types of star and star classes. However, I would still like the idea of supernovas or transformations of star forms (expansion as in red giants, or "deflation" as in dwarfs). Maybe in order to set the timing for their lifespans, you could add a command line to only certain stars, possibly ones that have already been detected by radio telescopes, at least in our time, and actually give certain time periods for them to exist in Celestia. Later on, for the fictional stars and the extrasolar catalogued stars, you could add once again a particular "existing limit". Don't get me wrong- I already realize this has been discussed earlier in the forums, but this should be something that should looked at in considerable aspects. In order to simulate the nuclear explosion, perhaps simply a realistic animation? I have also considered the effects it would have on the surrounding celestial bodies. Depending on how the supernova would cause the star to end, would it create a super gravity well, such as a black hole? Also, please excuse me if my terms are not correct, for I am only a fairly new person participating in the development of Celestia; I am not as familiar with the source codes, scripts, etc. I know this would be demanding on sytem requirements to simulate accurately such a cataclysmic event, it being a dynamic change for the entire universe of Celestia, at least at a different time period, depending on how the time is set. This also brings me to another idea.
Eversince I first discovered Celestia, I fell in love with it( I personally think it outdoes Microsoft Space Simulator, even though it lacks some features[graphics are superb compared to Space Simulator]). Now I have noticed that the Celestia universe seems to be, shall I say, somewhat stationary[i]. When I have been playing around with the program, I have sped up time to close to its maximum, and zoomed out to watch any movement of the stars whatsoever. I was disappointed to see that the stars only rotated on their axis, but no recorded movement of them throughout the Orion Arm in the Milky Way Galaxy was made. I know this is a beta version, and Celestia is nowhere near being finished, but it should be a thought for newer versions to come. The only movement I could see were objects with orbits, which included planets, moons, asteroids, comets, and spacecraft. All of these objects had something to orbit around- it is clearly stated in their .xyz locater file. Why can we not cause the stars to orbit around, say the nucleus of the Milky Way, if it were considered an actual object. I have only seen that it is only identified with a name, even in the galaxies.dat, and has no predicted movement in the Virgo Cluster. I know that our direction in space is very difficult to calculate; I do not know if it has ever been done, but maybe we should cause the galaxies themselves to have attributes.
Sorry for the length, but I just had to relay these suggestions.

What a relief!;-)
