Create an ethereal celestial garden floating in the night sky. The garden should be filled with luminescent flowers, each glowing with different hues of blues, purples, and pinks. Include delicate, intricately designed bridges made of stardust that connect various parts of the garden. Add small, mythical creatures like glowing fireflies and butterflies with transparent wings. The backdrop should be a starry night sky with nebulae and distant galaxies, providing a serene yet magical atmosphere.
