Create a stunning cosmic landscape that showcases the vast mysteries of the universe. The scene should include swirling nebulae in vibrant hues of purples, blues, and deep pinks, with distant galaxies glowing softly in the background. Massive planets with unique textures and vivid rings should orbit gracefully, casting long shadows. An ethereal glow should surround a supernova exploding in the distance, lighting up the surrounding starfield. Include a black hole at the center, pulling in celestial matter with spiraling energy. Shooting stars and asteroids add a sense of motion. The overall atmosphere should evoke awe and the infinite wonder of space.
