Valhalla Research scientists aboard the Dallas had begun the second phase of testing
a new, long-range jump gate that would have allowed travel beyond the confines of
the Sirius Sector -- and could have potentially opened the entire galaxy for
exploration. Unfortunately, an unforeseen concentration of dark matter along the
jump route created a feedback wave that not only destroyed the Dallas and everyone
aboard, but expelled huge masses of dark matter and radioactivity. A quarantine was
immediately erected across half the system -- not for security, this time, but for the
safety of anyone foolish enough to stray into the dangerous morass. The jump gate
itself sank into a monstrous singularity that still hangs at the edge of the Texas, an
evil, swirling eye, that casts its gaze upon the wasteland of Houston.
Quoted from the Liberty Overview, by Chris Todd. It just seems to be a wormhole of some type, probably similar to one of FL's current jump gates. There are plenty of theories in this thread, but I'm personally leaning towards the explanation that cmfalconer presented (which is that as there was no defined destination, it connected to the inside of a dark matter cloud and caused the incident). However, there are many valid ideas in here; it depends on how you want to look at it, I suppose.
