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 ...

Earth's magnetic field dramatically flipped roughly 41,000 years ago. We can now experience this epic upheaval, thanks to a clever interpretation of information collected by the European Space ...

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 ...

More than a decade of satellite monitoring has mapped Earth’s magnetic field as it subtly altered between 2014 and 2025 — and what scientists have learned is remarkable. The South Atlantic Anomaly, a ...

The European Space Agency’s Swarm trio of satellites has found that a weak region in Earth’s magnetic field, known as the ...

Using 11 years of magnetic field measurements from the European Space Agency's Swarm satellite constellation, scientists have discovered that the weak region in Earth's magnetic field over the South ...

LOS ANGELES -- Recent satellite observations have revealed the largest breach yet seen in the magnetic field that protects Earth from most of the sun's violent blasts, researchers reported Tuesday.

A weak spot in the Earth's magnetic field is growing over the South Atlantic Ocean, according to more than a decade's worth of satellite data collected by scientists. The magnetic field surrounding ...
