Scientists are working to solve a mystery of Earth’s molten outer core, which lies more than 2,000 kilometers beneath our ...

The liquid iron in Earth's outer core doesn't always behave as expected. When it changed direction in an unexplained way, ESA ...

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 ...

Discover how recent changes in Earth's outer core influence its magnetic field and reveal new geological patterns.

LONDON — 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 ...

Earth's magnetic field is generated by the churn of its liquid nickel-iron outer core, but it is not a constant feature. Every so often, the magnetic north and south poles swap places in what are ...

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 ...
