In case that you are wondering what these are, they are basically a small chance space encounter or what others might call, a space anomaly. The station will attempt to communicate with you and give you coordinates if you interact with it.
It will then give you a 16 hexadecimal digit. This represents the system’s universal address.
You can also use the No Man’s Sky Portals Decoder to input this and translate it.
There’s not much else to be said I’m afraid. 🙂
