Solar Superstorm Gannon: Plasmasphere Crushed
Overview: What happened during Solar Superstorm Gannon In a display that reminded scientists why space weather matters, a powerful geomagnetic storm—nicknamed Gannon—shook Earth’s near-space environment. Such solar superstorms are rare events, typically occurring once every 20 to 25 years, but when they strike, they illuminate the complex interactions between the Sun’s eruptions and our planet’s…

Rising CO2 and the Ionosphere: How Global Warming Could Disrupt Shortwave Space Communications
Global warming reaches new frontiers: space communications under threat As the planet warms, scientists are uncovering a surprising wrinkle in how climate change could affect our ability to communicate through space and near-space environments. A team from Kyushu University has found that rising carbon dioxide (CO2) levels in Earth’s atmosphere may cool the upper atmosphere…

CO2 Rise and Ionosphere: Threat to Space Communications
Rising CO2 and a Cooling Upper Atmosphere: Why Space Communications Could Be at Risk As global warming accelerates, researchers are turning their attention to how atmospheric changes affect the ionosphere, a region roughly 60 to 1,000 kilometers above Earth. A team from Kyushu University has found that higher carbon dioxide (CO2) levels, while warming Earth’s…
