Imagine a vibrant celestial observatory, bathed in soft pastel hues, where cheerful anime characters explore the cosmos. Gleaming telescopes and star charts surround them, while whimsical star constellations twinkle above. Characters, with expressive features and playful poses, point excitedly at a meteor shower, their eyes sparkling with wonder. The setting is dotted with floating, fluffy clouds and a rainbow-hued galaxy, creating an atmosphere of joy and curiosity.
