Several studies have predicted that not all geomagnetic reversals have been discovered, but it was unknown in which periods they might be hidden. Researchers led by the National Institute of Polar ...

After accounting for Earth’s rotation, gravity is slightly weaker beneath Antarctica than anywhere else on the planet. That ...

Although Earth is approximately spherical, its gravity field doesn't adhere to the same geometry. In visualizations, it more closely resembles a potato, with bumps and divots. One of the strongest of ...

The geoid (the surface of equal gravitational potential of a hypothetical ocean at rest) serves as the classical reference ...

A mysterious gravity dip beneath Antarctica is growing stronger, shaped by deep Earth forces over millions of years.

Modeling suggests slow thermal convection beneath Greenland's ice sheet may form plume-like distortions seen in radar data.

Earth-like planets have a thin crust, a large mantle (which contains a lot of molten magma), and a core. Inside these ...

Earth’s magnetic shield is shifting in dramatic ways. New data from ESA’s Swarm satellites show that the South Atlantic Anomaly — a vast weak spot in Earth’s magnetic field — has grown by nearly half ...

For most of deep time, spreading ridges released more carbon than volcano chains, changing how we interpret Earth’s climate history.

Deep inside the Greenland ice sheet, radar images have revealed strange, plume-like structures distorting the layering ...

The mechanisms underlying two important phenomena in the Archean—the emergence of continental crust and the presence of an exceptionally strong geomagnetic field—remain poorly understood. Notably, ...

Precious metals may be escaping from the planet’s core. This hotly debated subject could help us understand Earth’s evolution and determine whether life exists elsewhere in the Universe ...
