A magnetosphere forms around any magnetized object, such as a planet, that is immersed within a stream of ionized gas, called plasma. Because Earth possesses an intrinsic magnetic field, the planet is ...

Meanwhile, an ice-monitoring satellite had just received a software update to its navigation system, allowing it to observe the impact of the solar storm while also keeping a steady watch on the ice ...

It seems improbable that a satellite designed to monitor polar ice sheets and floating sea ice could accurately measure a disturbance in Earth's magnetic field. But that is just what ESA's CryoSat ...

Earth is constantly being hammered by charged particles emitted by the Sun that have enough power to make life on Earth almost impossible. We survive because Earth’s magnetic field traps and deflects ...

Magnetosonic waves represent a fundamental class of electromagnetic emissions prevalent throughout Earth’s magnetosphere, where they mediate energy transport and particle dynamics. These waves, which ...

An international team from Kanazawa University (Japan), Tohoku University (Japan), LPP (France), and partners has demonstrated that chorus emissions, natural electromagnetic waves long studied in ...

There is a constant outward flow of charged particles from the Sun. This flow, known as the solar wind, moves across space and reaches Earth every day.

Our planet’s magnetosphere has seen dramatic shifts across its history—even total reversals—but this recent wrinkle doesn’t pose a threat to life Earth’s magnetic field surrounds the planet, with ...

Scientists have detected something strange in Earth’s magnetosphere, some 100,000 miles away from the ground. Split-second bursts of energy known as chorus waves were found “chirping” in an area where ...
