Earth’s core has often been described as just a giant ball of iron and nickel. Now, a new study argues that it is also a ...

Seismic waves passing through the Earth have revealed that the inner core of our planet is now rotating out-of-sync with the layers above it. Update: As reported below, research from January 2023 ...

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 ...

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

TEMPE, Ariz. — Seismologists in recent years have recast their understanding of the inner workings of Earth from a relatively benign homogeneous environment to one that is highly dynamic and ...

University of Maryland scientists uncovered evidence of an ancient seafloor that sank deep into Earth during the age of dinosaurs, challenging existing theories about Earth's interior structure.

In Jules Verne’s classic 1864 novel “Journey to the Center of the Earth,” adventurers descend through an Icelandic volcano into a vast underground world populated by prehistoric creatures as they ...
