Possibly because of what someone else mentioned. If the game has to create a homeworld in a game with a limited number of sectors, it will do some strange things. Once during a P&N game, the Sergetti started out in a black hole system, 3 sectors from the center.

What I have seen the TDM Modpack aliens do is destroy all nebulas and then ignite stars in the center, just 'cause they can, I guess. ANd they will also create stars in the center of an organic infestation, maybe that's what you saw?
