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 ...

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 ...

Invisible yet vital, Earth’s magnetic field plays a crucial role in shielding the planet from harmful solar radiation and cosmic particles. Generated deep within the Earth’s molten outer core, this ...

Earth’s magnetosphere, once thought to have a simple electric polarity pattern, has revealed a surprising twist. New satellite data and advanced simulations show that the morning side of the ...

Earth’s magnetic field shields our planet from dangerous solar energy and damaging cosmic radiation, while the gravitational ...

High-energy particles called galactic cosmic rays (GCRs) bombard unprotected objects in space, often causing damage. Earth, however, is protected by its magnetic field, which creates a protective ...

Here’s what you’ll learn when you read this story: It used to be thought that there were more volatiles than expected in lunar soil because they escaped Earth before it had a stable magnetic field.
