Geophysicists from ETH Zurich and SUSTech, China, have demonstrated the dynamo effect of the Earth’s core in a model in which viscosity has no influence, as is the correct physical regime for the ...

Beneath roughly 5,150 kilometers of rock, liquid metal, and extreme pressure, Earth’s solid inner core sits at temperatures ...

Earth is fortunate in having a magnetic field: it protects the planet and its life from harmful cosmic radiation. Other planets in our solar system—such as Mars—are constantly bombarded by charged ...

Scientists have long known that Earth's core is mostly made of iron, but the density is not high enough for it to be pure iron, meaning lighter elements exist in the core, as well. In particular, it's ...

Earth cross section showing the classic distinction between crust, mantle and core. But new research shows Earth's structure is far more complicated and may change over time. Analyzing an unusual ...

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 ...

Researchers have found evidence that Earth's core is leaking gold and other precious metals, according to a new study. The vast majority (99.9%) of Earth's gold and other precious metals are hidden in ...

Deep beneath the Pacific near the equator, Earth’s outer core now flows east instead of west. Dynamics deeper within our planet’s core may help explain the change and what to expect in the near future ...
