Destroyed Star Gate in Mindjammer Universe

Hello out there, our group is forced to travel to a star system with a destroyed star gate with close proximity to the Zarus. What is known about destroyed star gates and their periphery? Is there a stronger field of radiation, is the whole star system destroyed? Is there a unstable spacetime environment, with a strange reality? Can there be something going on, we saw in the movie Event Horizon? Does the rules give us some advice here?

Does anyone made some experince with this setting, or was someone ever exposed to some kind of extented reality?

Thanks in advance.
