Prompt
A lone blue planet fills the frame with calm authority, set within a 16:9 panoramic crop that emphasizes horizontal sweep and horizon placement near the lower third of the frame. The atmosphere glows in layered bands that move from deep navy to bright cyan and pale violet, echoing #0B3D91, #2AA9D8 and #6F4CC1 while a soft halo of near-white #BFE8FF rim light outlines the limb. The air feels crystalline and thin with a faint veil of cosmic mist bending the auroral light into subtle streaks. Foreground surfaces on the planet appear unlettered and clean, with micro-markings reduced to abstract lines rather than readable typography. Focus is crisp on the planet limb and nearby atmosphere with moderate depth so that the near-field glow reads sharp against a gently softened starfield beyond. The lighting is cool and luminous, giving gentle separation to cloud layers and relief to the horizon band. Framing is wide and cinematic with an eye-level viewpoint and balanced negative space across the upper sky for visual breathing room. A solitary ring fragment and a distant moon act as story cues to imply system scale and orbital motion. Render in a painterly space-art style with subtle texture, soft grain, and smooth gradients to convey alien calm.
