Rare ‘Double’ Lightning Phenomena With Massive Red Rings Light Up the Alps
For a brief moment last year, northern Italy's night sky offered a spectacle rarely seen in a lifetime. From his home in Possagno, nestled in the Alps, photographer Valter Binotto captured an image showing two of Earth's rarest lightning phenomena occurring at the same time. Elves and sprites are forms of Transient Luminous Events (TLEs), which flash high above thunderstorms, lighting up thin upper-atmosphere air instead of zapping anything below.
