Deep beneath our feet, approximately 2,890 kilometers underground, lies one of Earth's most mysterious regions. The boundary between our planet's molten outer core and solid mantle acts like a massive ...

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 ...

The liquid iron in Earth's outer core doesn't always behave as expected. When it changed direction in an unexplained way, ESA satellites provided data on the direction of flow, helping scientists gain ...

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 ...

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 ...

Here’s what you’ll learn when you read this story: Precious metals are leaking out of Earth’s core into the mantle, a new study suggests. Scientists identified a particular isotope of ruthenium (Ru) ...

Picture all of Earth’s oceans, which cover about 70% of the planet and are mostly made of hydrogen. Now multiply that by nine. That may be the amount of hydrogen in Earth’s core, possibly making it ...
