Recent research has unveiled a previously unknown doughnut-shaped structure deep within Earth's outer core, potentially offering new insights into the planet’s magnetic field, which plays a ...

Although the geodynamo produces a very intense magnetic field, only about 1 percent of the field's magnetic energy extends outside the core. When measured at the surface, ...

Essentially, a big boost of energy was needed to drive the geodynamo and stop the magnetic field from collapsing—and the solidification of Earth's core would have done just that.

Life as we know it could not exist without Earth's magnetic field and its ability to deflect dangerous ionizing particles from the solar wind and more far-flung cosmic rays.

Earth's so-called "geodynamo", involving the movement of molten iron in the Earth's outer core, began 4.22 billion years ago, say researchers today in the journal Science.

The ‘geodynamo’ in the Earth's liquid outer core produces a magnetic field that dominates the large and medium length scales of the magnetic field observed at the Earth's surface1,2. Here we ...

Researchers at Caltech 'recreated' the pressure of earth's core - 17 million times the pressure we feel on the surface - by crushing iron between two diamonds.

While challenging, age and alteration aren't the biggest source of bias in studying the geodynamo. Models and Field Data Don't Agree. Start with the Jurassic—a time of terrible lizards, high carbon ...
