and to answer your question, when you look at the galactic map, look at the bottom left of the screen and you'll see coordinates. By using this information, you can decipher which direction to go until you reach the coordinates you want.

Found out where the coordinates are. In the Journey book or logs.
I managed to reach the Orion Colony, but the scenario is not finished.
