Create a mesmerizing artwork that captures the vast beauty and mysteries of the cosmos. Imagine a surreal celestial landscape with swirling nebulae in vibrant blues, purples, and pinks. In the foreground, a lone astronaut or a futuristic spacecraft drifts peacefully, gazing at an ethereal scene where planets of various sizes and colors align in a visually striking pattern. In the distance, massive rings of dust and light encircle distant stars, while shimmering comets and glowing constellations add to the sense of wonder. The artwork should evoke a feeling of awe, exploring themes of exploration, the unknown, and the infinite possibilities of the universe.
