Wandering Star System.
Both Earth and Green Star were equipped with a Superluminal Detector.
This most advanced type of detector to date is composed of a supercomputer and vibration sensors. The supercomputer is mainly used to analyze and calculate the position of the source of vibrations, as well as the mass and type of the material causing them, and then draw a ten-light-year-sized real-time 3D map on the computer screen.
The vibration sensors are used to receive space micro-vibration waves, arranged with thirty-six thousand independent femto-sized detection slices scattered in the space around the planet to capture micro-vibration waves nearby, then the frequency of these waves is fed back to the supercomputer for the final mapping.
Thus, a real-time 3D map is displayed on the screen of the Superluminal Detector.
