Astronaut Walking Towards Alien Desert Portal

the prompt

A solitary astronaut in a white spacesuit walks slowly through a vast, orange-hued alien desert landscape towards a colossal, glowing futuristic portal. In the background, a majestic, large alien moon dominates the twilight sky, casting dramatic light, alongside a distant futuristic city built into a cliff. The scene is hyperrealistic, cinematic, and epic, with a static camera view. The portal actively emits light, reflecting on the desert sand, and subtle clouds drift in the sky.
