A lone astronaut standing on the dark surface of an alien moon, staring at an enormous perfectly rectangular doorway floating vertically in space with no structure around it. Through the doorway is a bright tropical ocean at sunset with palm trees moving in the wind, warm golden light spilling onto the barren lunar ground. Earth is visible small in the distant sky.
