We considered the question of how our artificial constructions are visible to advanced extraterrestrial civilizations. Taking the universality of the laws of physics, we found that the maximum distance where the detection is possible is of the order of 3000 ly and under certain conditions Type-II advanced alien societies might be able to resolve this…
