  — In-Game Description 

Collapsing Stars are Stars that have been mined to depletion on the VEGA Federation, and are at the end of their lifespan, since they can go supernova any moment and decimate the entire sector with it.

They appear only during Alliance War, and are spawn points for Alliance War Targets.
