Earth’s inner core has long challenged researchers because seismic waves do not move through it uniformly. Compressional waves generated by earthquakes travel roughly 3 to 4 percent faster along Earth ...

With modern seismic tomography, Earth scientists have discovered that above Earth's core-mantle boundary (CMB), about 2,900 ...

Deep beneath our feet, far beyond the reach of any drill, new research suggests that Earth’s center is far more intricate ...

Earth’s deep interior still shapes the world above your feet. Water trapped far below the surface helps control how rocks move, melt, and recycle through the mantle.

One of the oldest unsolved riddles in planetary science concerns the origin of the moon. Over a century ago, George Darwin proposed that tidal and centrifugal forces on a rapidly rotating proto-Earth ...

In China’s Taklimakan Desert, engineers are drilling a scientific well over six miles deep to explore the Earth’s interior ...

China begins drilling a six-mile-deep scientific well named Shendi Take 1 to explore the depths of the Earth and its secrets.

New research reveals that Earth’s solid inner core is actually in a superionic state, where carbon atoms flow freely through a solid iron lattice. This unusual behavior makes the core soft, matching ...

Here's how the astronomical phenomenon influences our planet—from the length of our seasons to the way Earth moves through ...

Google has released the December 2025 core update, its third of the year. The rollout began December 11 and may take up to three weeks. Google released the December 2025 core update on December 11, ...

Our planet’s magnetosphere has seen dramatic shifts across its history—even total reversals—but this recent wrinkle doesn’t pose a threat to life Earth’s magnetic field surrounds the planet, with ...
