In June , scientists from Spain went in search of the ghosts. that crossed the skies of the Mediterranean Sea. Those green wisps, which danced on reddish-pink lightning at high altitudes during storms, were not discovered until May of that year. What were they? The only way to know was to capture one. But the task was going to be difficult. These ghosts have a very appropriate name : they are difficult to see with the naked eye and appear only for a second tens of kilometers from the earth. "Seeing a ghost is very difficult," said María Passas-Varo, a researcher at the Andalusian Institute of Astrophysics in Spain.
But on September 21, , they finally caught one Europe Mobile Number List with a specialized camera: a green spirit flickering in the crown of a jellyfish-shaped whirlwind of fuchsia lightning 80 kilometers above the sea. And after painstakingly unraveling the different wavelengths of light emitted by the ghost, the scientists revealed its elemental composition. Oscar Van der Velde shows a jellyfish sprite.

But the main contributing factor was another element.
It was a surprise, because metal came from space. Better understanding ghosts and other ephemeral lightning-like entities can help scientists interpret the chemistry and physics of Earth's upper atmosphere. difficult to decipher. Metals that dance in the sky "There are layers of metals that dance" in and above the storms, Passas-Varo explained. Ghosts are a type of transient light event , or ELT, which scientists first described in . ELTs can include blue jets, which shoot upward from storm clouds, as well as crimson-tinged lightning in the atmosphere. superior that can take many forms, such as carrots and jellyfish, and are known as Duende.
