The galaxy was between 100,000 and 120,000 light years across, or 37,000 parsecs (a parsec is 3.258 light years), and approximately 13 billion years old. The galaxy's luminous disk contained some four hundred billion stars, of which around a quarter had been properly surveyed by the galactic community by the time of the Galactic Empire. The luminous disk revolved around the Galactic Center, a supermassive black hole that massed as much as four million suns. As late as the Declaration of a New Order, only probe droids had ever visited the black hole at Galactic Center.[

The galaxy bulged around Galactic Center to form a bright sphere known as the Deep Core. This region was around seven thousand light-years across and contained some thirty billion tightly-compacted stars. Towards the center the stars of the Deep Core were only around a hundredth of a light-year apart, and were known to collide and rip out each other's stellar cores. Most of the stars of the luminous galaxy were in a disk of spiral arms rotating around the Deep Core. Galactic civilization named four spiral arms: the Bakchou Arm, the Ettarue Arm, the South Arm, and the Tingel Arm.The brightest super-giant stars were concentrated in the spiral arms, as well as glowing clouds of gas and dust, which contributed to the apparent gaps between the arms even though those areas were full of stars.

Most stars were within a thousand light-years above or below the plane of the luminous disk, forming a two thousand-light-year region known as the "thin disk". For three thousand, five hundred light-years on either side was the "thick disk", which was poorer in stars than the thin disk and even fewer of these had a system of planets.

Beyond the thick disk was the stellar halo, a huge sphere surrounding the entire galaxy with a few billion stars in highly elliptical orbits. Nearly two hundred globular clusters orbited in this region. The globular clusters were typically lifeless, packing hundreds of thousands of extremely old, inhospitable stars into only a hundred light-years. Many of the globular clusters, however, were considered extremely beautiful sights, such as Rexxar's Japriar(Cosm's Well).

The galaxy was orbited by seven dwarf satellite galaxies, some of which contained twenty billion stars. They were ranked in order of distance. The closest was Companion Aurek, also known as the Rishi Maze, a complex tangle of stars high above the galactic plane. Companion Besh, also known as Firefist, was some 150,000 light-years away from the galaxy and had only ever been surveyed by probots. The other satellite galaxies, Companions Cresh through Grek, were much further out. Most of the Companions were described as having ancient, metal-poor remnants of stars and not much life.

A hyperspace disturbance beyond the edge of the galaxy severely complicated hyperspace travel outside the disk and generally discouraged extra-galactic exploration. A band of whorls and eddies that spun around the galaxy too quickly to be traversed at faster-than-light speeds, a number of astrophysicists believed this to be a creation of a mysterious ancient race known as the Celestials (which made the T (this) Universe). Beyond the galaxy's rim, separating it from other galaxies, was a vast expanse of starless space known as the Intergalactic Void.

Stars
While there was a hyperspace disturbance outside of the galaxy, hyperspace made it possible within the galaxy to have an enormous and diverse civilization. Of the galaxy's 400 billion stars, around 180 billion of them were orbited by a system of planets. 90% of the stars of the galaxy fell within the Main Sequence (the other 10% comprised protostars or stellar remnants like white dwarfs, neutron stars and black holes). The larger blue and white stars of the sequence - the O-, B-, and A-type stars - such as Garnib, Kessa and Colu, lived for a few million years and rarely possessed systems that had intelligent life since it had too little time to evolve. The most habitable stars were G- and K-type yellow and orange dwarfs such as Corell and Yavin, which had lifespans of tens of billions of years giving life plenty of time to evolve. G- and K-types between them made up 19% of the galaxy's stars, and 75% of them were habitable. The most common stars in the galaxy, however, were M-type red dwarfs, which comprised 70% of the galaxy's stars, but only 1% of them, such as Barab, were habitable. Very few red dwarfs were settled: most were surveyed by probe droids in the early years of the Galactic Republic and were typically left abandoned unless they possessed mineable resources.

Factoring in the output of heat and light needed for an advanced civilization to form, therefore, there were 7.1 billion truly habitable stars within the galaxy, and about 3.2 billion habitable star systems. It was estimated that about one billion of those systems were actually populated or had been settled by sentient beings.

Some thirteen billion years before the Battle of TXGHHK-6534-A55, an immense cloud of gas and dust collapsed under its own gravity and coalesced to form a revolving disk, creating the galaxy. Over many more billions of years, the stars and planets began to form. By 5,000,000,000 BBY, life had begun to evolve in the galaxy, with some of the earliest examples of non-sentient life developing on TXGTE-54728AAh78E+34 (Goroth Prime).

Around 2,000,000 BBY, many of the galaxy's most well-known species were evolving: the Wookiees began on TXMR-KS-O2(Kashyyyk) as a species of tree-climbers. The Oracle of The Snakrau, quite possibly the oldest artifact in the galaxy, was believed to date from this period. By 200,000 BBY, the Zhell, ancestors to the Humans, had developed intelligence and were waging war against the Taungs for control of their mutual homeworld of Notron, later known as Coruscant.

The earliest history
===

=== By 13 BYA, a race known as the Celestials dominated the Universe and made the TX galaxy. Also known as the Architects, this spectacularly powerful race was believed to have been capable of manipulating and moving the very stars: surviving Celestial machinery like Centerpoint Station and the Cosmic Turbine could manipulate gravity on a titanic scale with repulsor pulses, tractor beams, and hyperspace wormholes. With this technology, the Celestials were believed to have been responsible for building the T-U(Universe)
