Which one cant do in ingame galnet, which further reinforces the point about ED being more of a browser-forum game...
Anyhow, not sure if it has been mentioned, but when viewed from the "bottom" of the galaxy (i.e. when when putting camera under galactic plane and looking up), new systems roughly repeat pattern of monolith locations in our known ruins (please note, that it was not my intent to align map screenshot perfectly, but rather to roughly illustrate my observation)

All 5 stars:

Some later speculations:
"Beacons with ancient relics"
B1 = Synuefe XO-P c22-17
B2 = IC 2391 Sector GW-V b2-4
B3 = IC 2391 Sector ZE-A d101
B4 = Synuefe XR-H D11-102 (current ruins)
That leaves Synuefe ZL-J d10-119 "outside" the pattern.
Also, it might be worth analyzing ruins construction around B1 and B4, because it might give us a hint which planet in Synuefe XO-P c22-17 contain ruins.
