Cosmic Roots: Astronaut's Vigil

This is a cinematic, surreal space scene where an astronaut floats across the vast expanse of space, with the vast Earth beside them. Earth occupies the left side of the frame, the astronaut is on the right, with legs bent and float backward, one arm reaching toward Earth. The astronauts wear realistic white EVA-style spacesuits, equipped with dark reflective masks, backpack devices, and red, yellow, and green epaulettes. The Earth is viewed from the Atlantic Ocean, with North and South America clearly visible. Against a deep, dark, starry backdrop, the Earth's edge emits a cool blue halo. On continents and even oceans, faintly visible organic, branching root systems or neural veins spread across the surface, especially dense in North America and extending into South America, creating a dark biomechanical or "living planet" effect. It employs dramatic understated lighting, strong contrast, melancholic shadows, photo-quality textures, ultra-fine cinematic realism, a quiet and oppressive atmosphere, and wide-angle compositions with large areas of blank space.
