Scientists Discover Rare Red Sprite Lightning Over Himalayas

Scientists documented over 100 red sprite lightning strikes above the Himalayas, providing new insights into high-altitude electrical phenomena and highlighting the region's unique geography in influencing storm dynamics. The event underscores the importance of citizen scientists in atmospheric research and advances understanding of how thunderstorms impact the Earth's upper atmosphere and climate.

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.

Decoding the Enigma of Atmospheric Ghosts: Scientists Reveal Surprising Findings

Scientists have discovered a possible explanation for the mysterious "atmospheric ghosts" phenomenon, which are green afterglows that appear above thunderstorm clouds. Using a special instrument called the Granada Sprite Spectrograph and Polarimeter (GRASSP), researchers found evidence of oxygen and iron in the composition of these ghosts. The presence of iron at lower altitudes than expected suggests that thunder or gravity waves may be disrupting its usual position. Further observations are needed to gain a clearer understanding of this phenomenon.

Astronaut Captures Rare "Red Sprite" Phenomenon from Space

Astronaut Andreas Mogensen captured a rare video of a red sprite, a type of Transient Luminous Event (TLE), hovering above a thundercloud from low Earth orbit. Red sprites are elusive and spectacular phenomena that occur above thunderstorms and have captivated scientists and sky-watchers. They were discovered in the late 20th century and are part of a family of upper-atmospheric phenomena linked to thunderstorm activity. Red sprites offer valuable insights into atmospheric electricity and upper-atmosphere conditions, but studying them remains challenging due to their unpredictability and brief lifespan. Continued research and observation promise to uncover more secrets about these ephemeral lights and deepen our understanding of Earth's atmospheric dynamics.
