Uncommon phenomena refer to rare events or occurrences that deviate from the norm, often capturing public interest due to their unusual nature. Examples include ball lightning, a mysterious electrical phenomenon that appears as glowing spheres during thunderstorms, and bioluminescence, where certain organisms like jellyfish and fireflies emit light through chemical reactions. These phenomena can also include auroras, which are natural light displays in the sky caused by solar wind interacting with Earth's magnetic field. Such events often inspire scientific research and curiosity, as they challenge our understanding of natural processes and the environment.
