A high-detail, cinematic shot of an astronaut floating in outer space with Earth's blue curvature and atmosphere in the background. The astronaut is wearing a realistic, weathered white space suit. They are holding a metallic thermos from which dark coffee or amber liquid is spilling out, forming perfect spherical droplets and a beautiful splash due to zero gravity. Dramatic lighting with strong sun glow reflecting off the helmet's visor and liquid droplets. 8k, hyper-realistic, photorealistic, cosmic atmosphere.
