Imagine a small Italian town, nestled in the shadow of the Alps, suddenly bathed in an eerie red glow—not once, but twice in three years. It sounds like the plot of a sci-fi movie, right? But this isn’t fiction; it’s real. On November 17, nature photographer Valter Binotto captured a bizarre, UFO-like halo stretching 200 kilometers across the sky, hovering at an altitude of 100 kilometers. This wasn’t the first time—in March 2023, Binotto spotted an identical phenomenon in the same spot: Possagno, a quaint town of just 2,200 people in northern Italy. So, what’s causing this otherworldly display? And this is the part most people miss: it’s not aliens.
According to Binotto, these mesmerizing halos are a rare atmospheric phenomenon known as ELVEs (Emission of Light and Very Low-Frequency Perturbations due to Electromagnetic Pulse Sources). In simpler terms, they’re created by the electromagnetic pulse (EMP) from lightning strikes interacting with the Earth’s ionosphere. These rings of light are fleeting, lasting just a millisecond, which makes them incredibly difficult to observe without advanced equipment. But here’s where it gets controversial: while ELVEs are scientifically explained, their appearance over the same tiny town twice in such a short time has left experts scratching their heads.
Binotto explains that the red ring marks the exact spot where the EMP hit the ionosphere. The lightning bolt responsible for this event carried an electrical current of approximately 303 kilo-amperes—10 to 30 times stronger than an average thunderstorm discharge. This isn’t your everyday lightning strike; it’s a powerhouse of energy.
ELVEs are part of a broader category called Transient Luminous Events (TLEs), first discovered by NASA in the 1990s. These are colorful, lightning-fast flashes generated by thunderstorms above the clouds, often taking whimsical shapes with equally whimsical names. On Earth, ELVEs appear reddish due to their interaction with nitrogen in the upper atmosphere. But on planets like Jupiter, where hydrogen dominates, they glow blue or pink. In 2019, scientists using data from Juno’s ultraviolet spectrograph instrument confirmed the presence of TLEs in Jupiter’s upper atmosphere—a discovery long theorized but never proven.
So, why Possagno? Is it just a bizarre coincidence, or is there something unique about this town’s location? Here’s a thought-provoking question for you: Could this phenomenon be linked to specific atmospheric conditions in the region, or is it simply a statistical anomaly?
