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 ...

Our planet's invisible shield is changing in ways that scientists are only beginning to understand. Over the past two hundred years, Earth's magnetic field has weakened by around nine percent on a ...

The South Atlantic Anomaly, a huge weak spot in the geomagnetic field off South America, has expanded and sprouted a lobe in ...

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 ...

Forbes contributors publish independent expert analyses and insights. David Bressan is a geologist who covers curiosities about Earth. Nov 28, 2025, 07:59am EST Map of the strength of the Earth's ...

The weak spot in Earth’s magnetic field, a region over the South Atlantic where the field’s strength is significantly reduced compared to its surrounding area, has grown by an area nearly the size of ...

Particles from Earth’s atmosphere have been carried into space by solar wind and landing on the moon for billions of years, mixing into the lunar soil, according to a new study.

Two enormous, supercontinent-sized 'islands' buried deep within the mantle have been revealed to have fundamental differences—contrary to previous assumptions—and they may even lead to Earth's ...

Lunar rocks are famously dry. They contain almost none of the volatile elements that easily escape into space, such as hydrogen, carbon, nitrogen, and light noble gases. Yet those same elements appear ...
