The circumferential hyperspace barrier, also known as the galactic barrier, was a chain of hyperspace anomalies on the edge of the galaxy and prevented hyperspace travel outside of it.
An entry point in the Outer Rim Territories known to the Yuuzhan Vong as Vector Prime was the only place known where the Yuuzhan Vong fleet could penetrate the energy field surrounding the galaxy. It was close to outer edges of the Dalonbian sector, near the Helska system.
The galactic barrier had a midline that was almost exactly corresponded to the portion of the Unknown Regions that bordered the "western" quarter of the galactic disc. This segment of the Unknown Regions was historically impenetrable to conventional hyperspace mapping attempts by the Galactic Republic.
Dr. Insmot Bowen of the Obroan Institute speculated in 1 BBY that the Celestials were responsible for the disturbance, possibly to contain their enemies due to a war occurring at the time. He nicknamed it the bubble.
