The Magnetic Shield That Protects Our Climate Earth is surrounded by an immense magnetic field, called the magnetosphere.

Traditionally, scientists believed that the charge polarity of the magnetosphere at the equator and the poles was the same, ...

A weak spot in Earth’s protective magnetic field is growing larger and exposing orbiting satellites and astronauts to more ...

The Earth’s magnetic field plays a big role in protecting people from hazardous radiation and geomagnetic activity that could affect satellite communication and the operation of power grids. And it ...

Stephen has degrees in science (Physics major) and arts (English Literature and the History and Philosophy of Science), as well as a Graduate Diploma in Science Communication. Stephen has degrees in ...

Geophysicists from ETH Zurich and SUSTech, China, have demonstrated the dynamo effect of the Earth’s core in a model in which viscosity has no influence, as is the correct physical regime for the ...

A new analysis of computer simulations of Earth’s magnetic field suggests that its behavior was different early in Earth’s history, resulting in greater stability and fewer reversals of the magnetic ...

Recent studies have revealed unsettling changes in Earth’s magnetic field that could threaten satellite operations and even lead to complete blackouts. This article explores the dynamics of the ...

A growing weak spot in the magnetic field surrounding the Earth could lead to satellite malfunction and even cause them to ...
