Create an anime-style book cover illustration with a stunning night sky of swirling galaxies, purple-blue nebulae, twinkling stars, and meteors on a navy-black background. At the bottom center, show a small observatory on a grassy hill, its telescope window facing forward. In front, depict three characters from behind, half-body: a 12-year-old girl in a dress, a 14-year-old boy with a light brown backpack and jacket, and a man in a long white coat between them. Characters are small, emphasizing the sky’s vastness. The scene glows softly, evoking wonder, highly detailed, A4 layout.
