Scientists in the United States have created a small device that produces a tiny electrical signal from Earth’s natural rotation. Although the voltage is extremely small, the experiment shows that ...

Earth’s magnetic field has long been framed as a planetary force field, a protective bubble that keeps the worst of the Sun’s ...

Scientists discovered Earth’s magnetic field is weakening over the Atlantic Ocean, but what does that mean for life on the ...

Particles that escaped Earth’s atmosphere accumulated on the lunar surface over billions of years. Here’s what you’ll learn ...

The Earth's magnetic field and oxygen evolved together over 540 million years, according to a major NASA study.

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 ...

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 ...

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 ...

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 ...

When the magnetic field around the Earth grows stronger, oxygen levels rise. That is the surprising finding of a new study looking at more than half a billion years of planetary history. Researchers ...

Geophysicists have modeled how Earth’s magnetic field could form even when its core was fully liquid. By removing the effects of viscosity in their simulation, they revealed a self-sustaining dynamo ...
