How can anyone defend a galaxy if they have no concept of what that galaxy truly is? A trooper given an order to commandeer a transport and get his squad to Turais must first know what constellation Turais was in. Of course, the trooper in question could rely on the officers of the Fleet to get him there, and indeed they should. However, with the knowledge that Turais was in the constellation Carina, also known as the Heel, and is in an area of space believed to be controlled by the Skinnies, the trooper would be able to prepare his men for the possibility of an encounter with these aliens. Information is both weapon and shield; a good trooper will never forget that.

With that in mind, a trooper will examine each world under the protection of the United Citizens’ Federation in exacting detail, eventually growing to know the planets of the UCF as if he had grown up on them. A trooper will know their installations, military bases, cultural traits, population numbers and standard defences, granting him an understanding equal to that of a Fleet helmsman. On the other hand, the galaxy is vast, so vast that, even with all the exploration undertaken by the Federation during its incredible longevity, less than 5% of it has been explored or even adequately observed. There is little doubt that there are other wonders and other races simply waiting to be discovered.

The Milky Way

The galaxy consists of about 200 billion stars, with the Terran sun, Sol, being a fairly typical specimen. It is a fairly large spiral galaxy and it has three main components – a disk, in which the Sol system resides, a central bulge at the core, and an all-encompassing halo. These components are of varying ages, but the determining factor for any galaxy’s age is the composite age of its halo stars. In the Milky Way, halo stars have a rough age estimate of 12 billion years. This, compared with other galaxies, renders the Milky Way a mature adult galaxy, nearly twice the age of nearby Andromeda (four to six billion years) but not nearly as old as Maelstrom (a galaxy with an amazing age of more than 90 billion years).

A note on the abbreviation kpc: This acronym stands for kiloparsec or 1,000 parsecs. A parsec is a distance used in interstellar travel; it equals 3.262 light years. To give a full understanding of just how far a single kiloparsec really is, consider the following: 1 kpc = 3.08568025 × 1019 meters. By this equation and the fact that a light year is 9,460,730,472,580,800 metres long, one can calculate in metres the width of the galaxy. (3.262 x 9,460,730,472,580,800 = 30,860,902,801,558,569.6 metres in a kiloparsec. This distance multiplied by 30 = 925,827,084,046,757,088 metres, the width in metres of the Milky Way. Just for sake of reference, 8.6 kpc is the distance from Earth to the centre of the Milky Way.
  • Disk

The disk of the Milky Way has four spiral arms and it is approximately 30 kiloparsecs wide and one kiloparsec thick. It is made up predominantly of Population I stars which tend to be blue and are reasonably young, spanning an age range between a million and ten billion years old.

  • Bulge

The bulge, at the centre of the galaxy, is a flattened spheroid ten kiloparsecs wide and two and a half kiloparsecs thick. This is a high-density region where Population II stars predominate – stars which tend toward red and are very old, about ten billion yearsor more in age.

  • Halo

The halo, which is a diffuse spherical region, surrounds the disk. It has a low density of old stars mainly in globular clusters (these consist of between 10,000 and 1,000,000 stars). The halo is believed to be composed mainly of dark matter, which may extend well beyond the edge of the Milky Way’s disk.
