Megastruktur Orbital Bulan Sabit di Atas Bumi

A cinematic hard-science-fiction space scene showing an enormous crescent-shaped orbital megastructure above [Earth]. The structure is a dark metallic incomplete ring shaped like a giant curved arc, featuring intricate layered panels, exposed trusses, scaffolding, antennae, docking spines, and thin mechanical ribs. At its center is a small glowing spherical hub emitting warm amber light, connected to the crescent by exactly three long articulated support arms, alongside a separate small curved module floating near the hub. The megastructure appears massive, industrial, and partially under construction, with subtle orange running lights along the frame and cold white highlights on black gunmetal surfaces. Below, the bright curved horizon of [Earth] fills the lower third of the frame, covered in pale clouds and atmospheric haze, while the upper two-thirds reveal deep black space with sparse, tiny stars. Wide-angle orbital perspective, dramatic scale, realistic high-contrast lighting, cinematic concept art photorealism. No text, watermarks, visible astronauts, or spacecraft.
