Earth’s magnetic field, generated deep within the planet’s liquid iron core, has been bending, stretching, and occasionally flipping for billions of years. That invisible shield determines whether ...

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 ...

An image of the Earth and moon comparing ocean tides (shown as a small blue ring) to plasmasphere tides (shown as a large orange ring) The moon exerts a previously unknown tidal force on the "plasma ...

Explore the hidden dynamics of Earth’s magnetosphere, a constantly spinning, living shield generated by the molten iron core beneath our feet. Learn how it has weakened by 30% over the last 3,000 ...

The magnetic fields that surround some planets, such as Earth, have been recreated in miniature in the lab. The 3D model may give us a better idea of how space weather affects satellites. Any ...

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 ...

Researchers at UCLA have discovered a new form of space weather – superfast electron rains that precipitate into the atmosphere from the radiation belts. The team says the events could affect ...

WASHINGTON, April 12, 2022 – 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 ...
