Earth’s core isn’t just a boring, featureless ball of metal, it turns out. A recent study used seismic waves from earthquakes to make a 3D model of the center of our planet, and the researchers ...

New research suggests that the Earth's solid inner core is softer and more dynamic than previously thought, changing ideas.

Deep beneath our feet, far beyond the reach of any drill, new research suggests that Earth’s center is far more intricate than a simple metal ball. Instead of a single solid sphere, the inner core ...

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 ...

Scientists used seismic data discovered Earth's inner core displays a variety of textures that it acquired will it formed from within the fluid outer core. The data set was generated over the past 27 ...

Deep beneath our feet, far beyond the reach of drills or submersibles, Earth hides a solid metal heart that behaves in ways geophysicists have struggled to explain. New experiments now suggest that a ...

The surface of Earth's inner core may be shape-shifting, new research suggests. The study, published Feb. 10 in the journal Nature, looked at earthquake waves that have skimmed the edge of the inner ...

The Earth’s inner core, predominantly composed of iron with a minor admixture of nickel and light elements, is a critical component in understanding our planet’s magnetic field and thermal evolution.
