This image shows the planet Uranus set against the blackness of space. The planet appears as a smooth, bright cyan disc at the center, its atmosphere reveals soft, hazy tones of blue. Surrounding the planet is a vivid reddish glow, forming a diffuse halo that contrasts strongly with the cool blue of the planetary disc. Encircling Uranus are several thin, concentric rings, visible as pale gray arcs. Subtle variations in brightness can be seen across the planet’s face, with slightly brighter patches near the limb, hinting at atmospheric structure.
