==== Outer Edge ====
==== Outer Edge ====
The star density in the galactic edge is very low. There are vast, empty voids of black space with rare, isolated [[Star system|systems]]. Thus individual star systems can be separated by long gaps of 40 to over 80 light-years. This requires a specialized high-jump-range exploration ship with an engineered [[Frame Shift Drive|FSD]] and premium synthesis materials to cross the Abyss gaps.
The star density in the galactic edge is very low. There are vast, empty voids of black space with rare, isolated [[Star system|systems]]. Thus individual star systems can be separated by long gaps of 40 to over 80 light-years. The spiral arms dwindle into the void of space. This requires a specialized high-jump-range exploration ship with an engineered [[Frame Shift Drive|FSD]] and premium synthesis materials to cross the Abyss gaps.


==== Galactic Disk ====
==== Galactic Disk ====
The galactic disk is the flat region that extends outward from the dense central bulge (center) to the sparse outer edge. The vast majority of star systems are located there including [[Sol]]. It also includes the spiral arms with lots of gas and dust.
The galactic disk is the flat region that extends outward from the dense central bulge (center) to the sparse outer edge. The vast majority of star systems are located there including [[Sol]]. The spiral arms with lots of stars, gas and dust. The Milky Way is a barred spiral galaxy, because the spiral arms are attached to the central bar of stars in the core. The 2 major spiral arms are the Scutum-Centaurus Arm ([[Inner Scutum-Centaurus Arm]] and [[Outer Scutum-Centaurus Arm]]), and the [[Perseus Arm]]. Minor-arms are the [[Orion-Cygnus Arm]], [[Sagittarius-Carina Arm]], [[Outer Arm]] and [[Norma Arm]].


==== Central Bulge ====
==== Central Bulge ====
The star density in the galactic center (central bulge) reaches extreme levels of tightly packed high-density areas (star cubes). The systems can be fractions of a light-year apart. There are thousands to millions of nearby stars. This causes severe performance loads on the in-game route-planner. The core has a high concentration of luminous B-type stars, Herbig Ae/Be stars, and surrounds [[Sagittarius A*]].
