3. The Mediterranean Red Sprites of 1997

On a research vessel in the Mediterranean Sea, a group of experts made a revolutionary finding in the summer of 1997. As they tracked thunderstorms around the area, they caught the first-ever colour pictures of a phenomena called “red sprites,” elusive, red-hued electrical discharges occurring well above thunderclouds.
Leading expedition researcher Dr. Elizabeth Gerhardt said, “We were absolutely stunned. These massive, red tentacles of light reached up into the stratosphere, lasting only for milliseconds but leaving an unforgettable impression.”
Scientists had never seen anything like the red sprites seen in the Mediterranean. Rising from 50 to 90 kilometres above the surface of the Earth, these ethereal crimson flashes seemed to dance above standard lightning strikes. According to team observations, the sprites sometimes resembled jellyfish or seemed as red light columns.
This revolutionary finding created an avenue of research in atmospheric electricity. Researchers discovered that the strong electromagnetic fields produced by strong lightning strikes in the troposphere below cause electrical breakdown in the mesosphere, thereby generating red sprites. Apart from verifying the presence of these elusive events, the 1997 Mediterranean observations provide vital information to grasp the intricate electrical processes taking place in Earth’s top atmosphere.
4. The Red Lightning of Mount Etna, 2013

Mount Etna, a historic volcano in Sicily, presented an amazing show of nature’s might one cold November night in 2013. Obsersvers were treated to an amazing display of red lightning arcing across the ash plume as the mountain rumbled to life in one of its most spectacular eruptions in years.
Local photographer Marco Restivo shot breathtaking pictures of the occasion, which soon went global. “It was like watching a battle between Titans. The red lightning bolts seemed to be fighting against the darkness, illuminating the ash cloud in a hellish glow.” he said.
A phenomena called volcanic lightning produced the crimson lightning seen during the Etna eruption. The violently expelled ash and rock particles smash to produce static electricity as they fly from the volcano. The colour of the lightning can be affected by the presence of some minerals and gases in the plume, therefore producing the uncommon and amazing red colours seen that evening.
Researchers of the event observed that the red lightning gave important new perspectives on the composition of the volcanic plume and the great electrical activity inside it. Showcasing the raw strength and beauty of our planet’s geological processes, the Etna eruption of 2013 is among the most visually arresting and scientifically important red lightning episodes in recent history.
