Ultra-realistic image that combines the concepts of yin and yang, sun and moon, night and day. Place a beautiful translucent volumetric glass ball with a smooth, shiny texture in the center of the composition, which has a slight rainbow effect on the surface. The transparent glass of the ball should reveal a volumetric internal mixture of yin and yang: on one side, a bright sunny morning with golden rays of light breaking through light, fluffy clouds, creating a feeling of warmth and joy. On the other side, a mysterious moonlit night, strewn with sparkling stars and soft silver light, evoking a feeling of calm and tranquility. Add magical elements to the background: light, translucent clouds that move smoothly, and twinkling stars that create a sense of depth and infinity. Use abstract lighting effects, such as soft glowing halos around the ball and sparkling particles that add dynamics and mystery. The background should be slightly blurred to focus attention on the ball and its contents, using soft gradients from bright gold tones to deep blues to emphasize the contrast between day and night. Create an atmosphere of harmony and balance, conveying the emotion of unity of light and darkness.
