Unveiling the Secrets of Atmospheric Green Ghosts: Spectrographic Analysis Reveals Surprising Findings
Scientists in Spain have conducted the first spectroscopic analysis of a rare atmospheric phenomenon known as "ghosts," which are a form of transient luminous event (TLE). These TLEs occur above thunderstorms and include various electrical events such as sprites, halos, elves, blue jets, and gigantic jets. The researchers observed a green glow above energetic sprites, which they named "ghosts." Through spectrographic analysis, they identified atomic oxygen, molecular nitrogen, and traces of atomic nickel, iron, sodium, and ionic silicon as contributing factors to the phenomenon. The findings suggest a need to revise current theories and models of TLEs.
