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, ...

Earth’s inner core has long puzzled scientists because seismic waves move through it unevenly. Compressional waves from earthquakes travel about 3 to 4 percent faster along the planet’s rotation axis ...

Earth's core contains up to 45 times more hydrogen than the oceans do, making it the largest hydrogen reservoir on the planet, a new study suggests. Researchers found that this vast amount of hydrogen ...

New research suggests that Earth’s solid inner core might not be as rigid as once believed. Instead, it could exist in an unusual “buttery” state of matter, one that challenges long-standing ...

Earth’s core, the deepest part of our planet, is characterized by extremely high pressure and temperature. It is composed of a liquid outer core and solid inner core. The inner core is formed and ...

Our planet’s core is made mostly of iron, but it might also contain primordial helium that formed just after the Big Bang. Helium normally has trouble bonding with other elements, but researchers were ...

PCWorld reports that scientists discovered Earth’s inner core has slowed its rotation relative to the crust, even appearing to stop moving in a phenomenon that occurs every 35 years. This iron-nickel ...
