TREK TRIVIA:

  At the center of our galaxy the planet {QI'tu'} is surrounded by the Great Barrier (veH tIn), an immense energy field (HoSchem) which imprisons the God-Being (ST5).  Later an "enhanced" Reginald Barclay took the Enterprise-D to the center of the galaxy to visit the Cytherians, some 30,000 light years away. A large glowing cloud was visible in the distance, possibly the Great Barrier. (TNG "The Nth Degree")
