Astronaute à la dérive près d'une Terre vivante

Cinematic surreal sci-fi scene of [a lone astronaut] floating in open space beside [Earth]. Wide composition with vast negative space; the planet dominates the left frame, while the astronaut drifts on the right side, floating backward with bent legs and one arm reaching toward the globe. The astronaut wears a realistic white EVA spacesuit featuring a dark reflective gold-tinted visor, life-support backpack unit, and a shoulder patch in [red, yellow, and green]. Earth is shown from the Atlantic perspective with [North and South America] clearly visible, rim-lit by a cool blue atmospheric glow against an inky black starfield with sparse distant stars. Across the continents and faintly over the oceans, intricate organic root-like and neural vein structures spread across the surface, creating an ominous biomechanical living-planet effect. Dramatic low-key lighting, deep contrast, moody shadows, photorealistic textures, quiet eerie atmosphere.
