Don't worry, this isn't a spoiler. The Star Control map is based on a 2D projection of the real universe going out around 130 light years.
You might enjoy this as it took some effort to try to create a reasonably accurate depiction of where we are compared to other stars. One major change from real stars is that we took the liberty of naming some of the stars ourselves because a lot of the ones that have been discovered in recent years have alpha numerical names.
So for example, one group of stars is known as the Trombley constellation in honor of our friend and colleague Sarah Trombley who was the lead developer on Ashes of the Singularity: Escalation.
