Decoding the Enigmatic Green Ghosts of the Sky

Scientists have captured new imagery of atmospheric phenomena known as "ghosts" that occur during some lightning storms. These green-hued wisps, which are difficult to see with the naked eye, were found to be composed of excited oxygen, nitrogen, and iron delivered from space. The discovery of the elemental makeup of these ghosts provides insights into the chemistry and physics of Earth's upper atmosphere. These transient luminous events, including ghosts, are still not well understood, but further research will continue to unravel their mysteries.
