太空人小隊穿越溪流前往遠古外星遺跡

A highly detailed, ultra-realistic photograph of a team of astronauts exploring ancient alien technology ruins. In the foreground, a shallow rocky stream with clear water and wet stones reflects the surroundings. Several astronauts in realistic white and gray space suits with backpacks and helmets walk carefully through the water, moving deeper into the structure as an exploration team. Dominating the scene is a massive circular alien ruin — a colossal, weathered archway and ring-shaped structure made of ancient unknown metal and stone, covered in intricate alien glyphs, eroded panels, glowing residual energy lights, and signs of extreme age and decay. The structure frames a spectacular view of distant jagged mountains, green vegetation, and a large blue-white planet or moon hanging in a bright cloudy sky. Lush trees and plants have grown among the ruins, emphasizing that this is a long-abandoned alien relic. Soft natural daylight illuminates the scene with volumetric light rays. Hyper-realistic textures of metal corrosion, water reflections, spacesuit materials and foliage, cinematic composition, photorealistic, 8k resolution, no text, no watermark.
