Interesting renderings here.

Looks like some sort of Celestia-like simulation, but there's certainly some very nice graphics on this one that would be nice to see in Celestia.

Bjorn is indeed one of the people generating excellent renderings of space objects. Note that he doesn't do realtime renderings, though, so not all of his techniques are applicable to Celestia.

Very nice graphics involved in the link. Too bad it can't show this graphic in Celestia. It would have been awsome.
