宇航员与“生命地球”

A cinematic surreal space scene showing 1 astronaut floating in open space beside Earth, with the planet dominating the left side of the frame and the astronaut on the right, drifting backward with bent legs and one arm reaching toward the planet. The astronaut wears a realistic white EVA-style spacesuit with a dark reflective visor, a backpack unit, and a shoulder patch in red, yellow, and green. Earth is shown from the Atlantic side with North and South America clearly visible, lit by a cool blue rim glow against a deep black star field with sparse tiny stars. Across the continents and faintly across the oceans, organic branching root-like or neural vein structures spread over the surface, especially dense across North America and extending into South America, creating a dark biomechanical or living-planet effect. Use dramatic low-key lighting, strong contrast, moody shadows, photorealistic textures, ultra-detailed cinematic realism, a quiet ominous atmosphere, and a wide composition with large negative space.
