The Earth's magnetic field is essential to life as we know it. But it’s something we can never see – or hear, until now. In a recent study released on Oct. 10 by the European Space Agency ...

Researchers have discovered that changes to Earth's magnetic field can happen incredibly quickly—10 times faster than we thought. Now it's just showing off.

Roughly 41,000 years ago, Earth’s magnetic field did something spectacular—it weakened dramatically, nearly collapsing before rebounding. This event, known as the Laschamp Excursion, lasted ...

Supercomputer models of Earth's magnetic field. NASA. Around 3,000km (1,900 miles) below our feet—270 times further down than the deepest part of the ocean—is the start of the Earth's core, a ...

Earth's magnetic field can be thought of as a huge cocoon, protecting us from cosmic radiation and charged particles that bombard our planet in solar wind. Without it, life as we know it would not ...

The German Champ spacecraft measured Earth's magnetic field from orbit between 2000 and 2010. It was succeeded in 2013 by the Swarm trio of satellites operated by the European Space Agency (Esa).

These rocks offer evidence that Earth had a strong magnetic field 3.7 billion years ago, but scientists aren't sure where that field could've come from. A 3.7-billion-year-old record of our planet ...

The Earth’s magnetic field is currently weakening, and there’s been a lot of talk in recent years that a reversal might be imminent. Now a new study has looked at the history of these events ...
