The movements within Earth’s molten core have been resisting efforts to understand them for a long time, but agreement between a mathematical and physical model has led two physicists to claim they ...

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 ...

The oldest firm age yet for Earth's magnetic field suggests that it developed before a solid planetary core, 3.7 billion years ago. When you purchase through links on our site, we may earn an ...

The iron-rich core at the center of our planet has been a crucial part of Earth's evolution. The core not only powers the ...

The Earth’s magnetic field briefly collapsed, leaving life on Earth exposed to increased solar and cosmic radiation. This ...

A new analysis of computer simulations of Earth’s magnetic field suggests that its behavior was different early in Earth’s history, resulting in greater stability and fewer reversals of the magnetic ...

Geophysicists from ETH Zurich and SUSTech, China, have demonstrated the dynamo effect of the Earth’s core in a model in which viscosity has no influence, as is the correct physical regime for the ...

A quiet but measurable shift in Earth’s gravity field between 2006 and 2008 has baffled scientists for years. Now, nearly two ...

A recent study reveals dynamic transformations in Earth's lower mantle, impacting both earthquakes and the magnetic field.

New work from Carnegie’s Peter Driscoll suggests Earth’s ancient magnetic field was significantly different than the present day field, originating from several poles rather than the familiar two. It ...
