Like many other elite players, I'm an amateur astronomer, and this particular pattern is clearly visible in the Sagittarius constellation (is a bit west of the galactic plane, so it stands alone). Right now it is visible when the sun sets.
I read in one of the threads something about the curious arrangement of the data points and how they make an arrow, but the problem was the fact that since the planet rotates, it projects a disk in the space. But by looking at the pattern, I just notice the similarities to the one on Sagittarius. When I consulted my astronomy software (Stellarium), the name Terebellum appeared. It is probably a mere coincidence, but since Elite loves such mysteries, well, here's the Tinfoil Theory.
BTW, Terebellum is also called Omega Sagittarii
Clarification acknowledged. Thank you! It may be worth having a look, who knows.
