 * This page contains some basic details about a couple of galaxies which a Spore-based fiction could use.



The Universe consists of uncountable galaxies. Here are a few of the most important ones. Note that the majority of galaxies are uninhabitable ones, mainly dwarf galaxies and irregular galaxies (and the two categories often overlap), which are not likely to develop life, so this page only deals with the larger and more structured spirals.



Spore Galaxy
The Spore Galaxy is a spiral galaxy with five arms. Due to its unusual features, the Spore Galaxy is believed to be artificial. It only has around half a million main sequence stars, mainly red and yellow dwarfs along with some larger giant stars, which is only 1% of its already low total star count. The majority of astonomical objects in the galaxy are stars such as brown dwarfs, along with stellar remnants and degenerate stars, which bring the total number of stars up to about 50 million. All black holes in the galaxy have been modified and converted into wormholes. The galaxy itself is also remarkably thin, having an average thickness of only 20 parsecs, although even this does not account for its low number of stars (a mere 1% of the expected number for a galaxy of its volume).

Girdo Galaxy
The Girdo Galaxy is a spiral galaxy with two arms: the Northern Arm and the Southern Arm. The Northern Arm starts on the left-hand side of the picture to the right, and has an unusually wide base in comparison to both the Southern Arm and to galactic arms in most other galaxies. It is the closest galaxy to Spore, located 0.5 megaparsecs away. Ancient records suggest that it was home to an alien race known as the "Xyanxes".

The Girdo Galaxy also has hundreds of globular clusters in its halo, within fifty thousand parsecs of its main disc, and many of them contain enough stars to almost be thought of as satellite galaxies in their own right. A few of the largest ones have gathered nebulaic gas, becoming capable of forming their own stars and terrestrial planets.
