Earth is fortunate in having a magnetic field: it protects the planet and its life from harmful cosmic radiation. Other planets in our solar system—such as Mars—are constantly bombarded by charged ...

Research shows Earth’s magnetic field may have formed with a fully molten core - protecting the planet long before the inner ...

Magnetic field data collected by ESA's Swarm satellites and other sources has been coverted into these frightening sounds.

For more than 100 years, scientists have puzzled over whether the Earth’s magnetic field had already been generated stably back in its early days when its inner core was fully liquid – unlike it is ...

Earth’s inner core is a hot, solid ball—about 20% of Earth’s radius—made of an iron alloy. The planet’s outer core, beneath the rocky mantle, is a colder, liquid metal. Geophysics models explain that, ...

The Earth’s magnetic field is considered vital for life, or at least any life more advanced than bacteria. Similar fields are one of the major things we look for when seeking habitable planets.

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 ...

Then, shortly after the predicted timing of the core solidification event, Driscoll’s dynamo simulations predict that Earth’s magnetic field transitioned back to a “strong,” two-pole one.

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 ...

Earth's magnetic field dramatically flipped a little more than 40,000 years ago. We can now experience this epic upheaval, thanks to a clever interpretation of information collected by the ...

The magnetic field arises as a result of interactions in the Earth’s iron-rich core, which consists of a solid inner core and a fluid outer core. The flow of heat from the core drives fluid motions in ...
