Long-term satellite measurements show that Earth’s magnetic field is changing faster and more unevenly than expected, driven ...

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 ...

Deep beneath our feet, something extraordinary is happening. Scientists have discovered that changes in Earth's core are directly influencing our planet's magnetic field in ways we're only beginning ...

During a brief but dramatic chapter in Earth's history about 41,000 years ago, the planet’s magnetic field nearly collapsed. What followed was a cascade of environmental and biological changes that ...

Space is full of radiation. So much radiation, in fact, that the only thing standing between us and our planet being bathed in radioactive energy from the Sun is the Earth's magnetic field. And this ...

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 ...

Ancient bricks may be key to understanding Earth’s variable magnetic fields. Scientists examined the iron oxide levels of 3,000-year-old bricks to understand the level of magnetism the bricks were ...
