Omicron Sector after the Neutron-S missile test created the Black hole
Omicron Sector was the location where the SDF-3 and the science vessel Deukalion conducted a test of the Neutron-S missiles on an uninhabited planet. Not realising the devastating potential of the weapon, both ships were badly damaged during the detonation of the weapon, which created a Black hole.
