Астронавт, обнаруживший окаменевшее космическое божество

A lone [astronaut] standing inside a colossal abandoned alien temple on a dark moon, discovering the gigantic petrified skeleton of a [forgotten cosmic god] stretching across the horizon. Glowing distant galaxies visible through fractures in the ceiling, floating debris drifting in low gravity, and mysterious glowing runes etched into ancient black stone walls. Deep cinematic shadows, [blue] volumetric lighting, immense sense of scale, atmospheric sci-fi horror realism, haunting and surreal aesthetic.
