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 ...

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 ...

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 ...

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

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 ...

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 ...

Today’s aurora alert proves the Sun is more dynamic than many may realize. The National Oceanic and Atmospheric Administration’s Space Weather Prediction Center announced today that the Sun had ...

A fast-moving stream of solar wind from a coronal hole on the sun is sweeping past Earth this weekend, raising the chances of visible auroras across northern-tier U.S. states on the nights of March 14 ...

The Moon may preserve a chemical record of Earth’s ancient atmosphere, and those same materials could one day support future lunar missions.
