Megastructura orbital antigua con núcleo de energía brillante en el espacio

A colossal ancient futuristic orbital megastructure floating in deep space, enormous bronze mechanical ring portal occupying the central frame, intricate inner gears and industrial architecture, giant glowing amber energy sphere suspended in the center, cinematic diagonal truss bridge crossing from lower-left foreground toward right-middle frame through the sphere, low-angle camera looking upward 25 degrees, slight camera roll 8 degrees, ultra wide 24mm lens perspective. Massive gas giant planet positioned in the upper-left quadrant, partially silhouetted against an immense golden-white stellar light source. Swirling cosmic nebula clouds wrapping behind the ring structure, dense interstellar dust, scattered asteroids drifting across the upper space. Powerful stellar explosion glow emerging from the right side of frame, intense volumetric god rays cutting through the portal and sphere.
