Antigua ciudad alienígena alzándose sobre una luna desolada y llena de cráteres

An ancient alien city, built with impossible geometric structures that defy gravity, rises from a desolate, cratered moon. The city is bathed in the eerie glow of a distant, binary sunset. This is depicted in the style of hard science fiction concept art, emphasizing realistic textures and a sense of immense scale, reminescent of popular science fiction art.
