NASA monitors the South Atlantic Anomaly, a growing magnetic field disturbance affecting satellites and spacecraft.

The magnetic barrier that protects Earthlings from radiation almost collapsed some 565 million years ago. Here’s what saved it.

Earth’s magnetic north pole is on the move—and in surprising ways. With the release of the World Magnetic Model 2025, ...

The National Aeronautics and Space Administration has been monitoring the Earth's magnetic field for a very long time and ...

NASA is keeping an eye on a massive “dent” in Earth’s magnetic field that could put an end to humanity as we know it.

Lunar rocks retrieved by China’s Chang’e-5 mission reveal that the moon’s magnetic field lasted much longer than scientists ...

NASA has turned its focus to a puzzling phenomenon in Earth’s magnetic field that could have an effect on life as we know it.

NASA has been monitoring a strange anomaly in Earth's magnetic field: a giant region of lower magnetic intensity in the skies ...

The Earth's magnetic field is essential for sustaining life, as it shields the planet from cosmic radiation and solar wind. It is generated by the geodynamo effect.

NASA is closely monitoring the South Atlantic Anomaly, which is a growing dent in the Earth's magnetic field that allows charged solar particles to approach the surface. A huge 'dent' anomaly in the ...
