The magnetic bubble surrounding Earth has an unexpected revelation from satellite data: the morning side of the magnetosphere sports a negative electric charge, not the positive one scientists ...

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 ...

Earth’s magnetosphere, once thought to have a simple electric polarity pattern, has revealed a surprising twist. New ...

Scientists have discovered that Earth’s magnetosphere is charged opposite to what was once believed. The area of space influenced by Earth’s magnetic field is called the magnetosphere. Within this ...

The presence of heavy ions in Earth’s magnetosphere alters the mass loading of the plasma, affects wave generation and propagation, and impacts the formation and transport of other energetic ion ...

A screen shot from NASA’s Scientific Visualization Studio that visualizes the Earth's magnetosphere being hit by a geomagnetic storm that happened throughout May 10-11, 2024. The powerful geomagnetic ...

More than a decade of satellite monitoring has mapped Earth’s magnetic field as it subtly altered between 2014 and 2025 — and ...

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 ...

Sunspot activity increases on November 1, 2025, as new regions emerge on the Sun. Solar flares, coronal mass ejections, and ...

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 of scientists has proved that Mercury, our solar system’s smallest planet, has geomagnetic storms similar to those on Earth. The research by scientists in the United States, ...
