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 ...

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

Earth's inner core may be layered like an onion, with silicon and carbon creating distinct zones that explain seismic wave ...

When Santa is done delivering presents on Christmas Eve, he must get back home to the North Pole, even if it’s snowing so ...

Neuroscientists have been trying to understand how the human brain supports numerous advanced capabilities for centuries. The ...

The iron-rich core at the center of our planet has been a crucial part of Earth's evolution. The core not only powers the magnetic field which shields our atmosphere and oceans from solar radiation, ...

What is the speed and timing of the Earth’s inner core cooling? This is what a recent study published in Nature Communications hopes to address as a team of scientists investigated the composition ...

Scientists have discovered that Mars has an interior structure similar to Earth's. Results from NASA's InSight mission suggest that the red planet has a solid inner core surrounded by a liquid outer ...

Earth's inner core, the solid iron-rich mass at the center of our planet, is slowly growing as the surrounding molten outer core cools and freezes. But this process has been a source of debate amongst ...

Researchers in England believe carbon played a key role in freezing Earth’s core. As it contributes to the cooling and freezing of the molten outer core, the solid, iron-rich center of Earth continues ...

CAPE CANAVERAL, Fla. — Scientists revealed this week that Mars’ innermost core appears to be a solid hunk of metal just like Earth’s. The Chinese-led research team based their findings on seismic ...
