Surreal celestial horse galloping through deep outer space

A breathtaking, high-concept celestial surrealist artwork of a majestic horse galloping through deep space. The horse's powerful muscular frame is seamlessly woven from dark blue starry nebulae, glowing cosmic clouds, and glittering distant galaxies. Its flowing mane and tail transform into blinding golden comet tails and stardust streams as it bounds forward. High contrast with the pitch-black void of space, ethereal internal glow, magnificent scale, sharp focus, 16k resolution.
