In Star Trek, the Amargosa Diaspora is an enormous globular cluster of unusually high density. One of its formations is FGC 13, a stellar cluster. In the Star Trek: The Next Generation episode "Schisms", the USS Enterprise-D charted this region with the long-range sensors, which attracted the attention of solanagen-based lifeforms to the ship. Amargosa was also the primary star of the Amargosa system, studied by a Federation observatory where Dr. Tolian Soran developed his trilithium weapon in the movie Star Trek: Generations. From the observatory, Soran launched the weapon into Amargosa in 2371 and collapsed the star, producing a level-12 shock wave that destroyed everything in the system. It is unknown if the collapse of the Amargosa star developed a quantum singularity, a dwarf star, or completely destroyed it.

The term 'diaspora' refers to the the spatial  property of being scattered about over a range or area. There is no such globular cluster as the Amargosa Diaspora in real astronomy. However, the jumbled rocks of the Virgin Spring area in the Black Mountains of the United States is complexly faulted and folded, and this part of Death Valley  has been named by geologists as the ‘Amargosa chaos'. These multi-colored and oddly-shaped mountains look as if  Mother Nature had scattered and thrown them together in a most twisted and random manner.

The FGC referred to in FGC 13 above stands for Federation General Catalogue. The real-science equivalent is NGC (New General Catalogue) - a well-known catalogue of deep sky objects in amateur astronomy. NGC 13 in this catalogue is a spiral galaxy in the Andromeda constellation.
