A Reddit user has shared a rare and striking photograph of a phenomenon known as a "fire rainbow"—an optical illusion that appears as a luminous, rainbow-colored arc in the sky. Unlike traditional rainbows, this spectacle forms when sunlight refracts through ice crystals in high-altitude clouds, creating vibrant, fire-like patterns without any actual flames. The image captures the fleeting moment of this natural wonder, offering a glimpse into the atmospheric conditions required for its formation. Meteorologists and sky-watchers often consider such displays a rare treat, typically visible only under specific weather circumstances.
