Medium shot focused on a mysterious alien structure made of smooth, black obsidian-like material with faint glowing geometric etchings, partially buried in red alien sand. An astronaut stands at the edge of frame looking up at it for scale. Stark lighting, ancient and artificial look. Cinematic, detailed texture, photorealistic. --ar 9:16 --raw --sref 277682627 --profile a4h3pmb --sv 4 --stylize 150 --v 7.0
