AI prompt: Write a story about a young astronomer who spends her days gazing at the stars through her telescope, dreaming of the wonders of the universe. One day, she notices an unusual rainbow-colored comet streaking across the sky, and she becomes obsessed with uncovering its secrets. As she ventures out into the rain to follow the comet, she realizes that she has forgotten her umbrella. Drenched to the bone, she is about to give up her search when she meets a stranger who offers her an old and tattered umbrella. With her new friend's help, the astronomer sets out to uncover the secrets of the comet, following it across the countryside and through a series of strange and wondrous events. Will they be able to unlock the secrets of the rainbow comet and discover the wonders of the universe, or will their journey be cut short by the forces that seek to keep the secrets of the cosmos hidden forever?
Ellie's prompt: A special telescope allows one to see doorways to other worlds hidden in rainbows. The only way to get through these doors—and back out—is with an umbrella, which may be more marvelous than the hidden worlds themselves.
