In a new paper published in Physical Review X, researchers present compelling evidence for a “helicity barrier”—a previously ...

Have we finally solved mystery of magnetic moon rocks? Simulations show how effects of asteroid impact could amplify the early Moon's weak magnetic field.

For the study, the researchers used computer models based on data obtained from NASA’s now-retired Mars InSight lander to simulate conditions within the interior of Mars depicting the absence of an ...

First ever supercomputer simulations of Mars with a fully molten core could explain the Red Planet's unusual magnetic field. Billions of years ago, Mars had an active magnetic field. Mysteriously ...

The planet's once-strong magnetic field appears to have been limited to its southern hemisphere, the apparent result of a fully liquid inner core that differs from that of Earth ...

Researchers studying decades of earthquake data say they have found the first evidence that, in addition to spinning backward, Earth’s inner core in changing shape.

The Earth's magnetic North Pole is currently moving toward Russia in a way that British scientists have not seen before.

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, ...

How Magnetic Fields Control Flow Within Earth’s Core Strangely, it seems the planet behaves magnetically as if there was a cylinder at its core, not a sphere.

A doughnut-shaped region thousands of kilometers beneath our feet within Earth's liquid core has been discovered, providing new clues about the dynamics of our planet's magnetic field.

ANU geophysicist Professor Hrvoje Tkalčić says that the dynamics of Earth's magnetic field is an area of strong interest in the scientific community. A doughnut-shaped region thousands of ...
