Well, we know New Eden cluster, K-space with their (supposed) binary stars for stargate anchoring, and uncharted space that has never been explored but that I assume is still in the same stellar entity, the New Eden galaxy, which seems to be a small one.
But what of other galaxies ? Do we know if PF or if there are other galaxies to be seen around ? Or are we in some sort of small singularity in the middle of nothing ?
