Generate an image of a vast desert landscape under a starry night sky. The sand dunes should be golden and rippling, with intricate patterns created by the wind. In the distance, there should be a solitary cactus or two standing tall against the backdrop of the stars. Use deep blues and blacks to depict the night sky, with plenty of stars and perhaps even a few planets visible. Create an atmosphere of peacefulness and wonder, capturing the sense of isolation and grandeur that comes with exploring the desert at night.
