Scientists have uncovered new information about the Earth's core: it may not be completely solid. Instead, its center may be more malleable than expected and has changed shape in recent years.

Earth’s inner core — like a planet inside another planet ... in the deep-Earth-seismology community about which one is real.” Tkalcic said the research from Vidale’s team tries to ...

Why Trust Us? A new study analyzing decades of seismogram data shows that physical changes can occur at the surface of the Earth’s inner core. This means that the surface of the inner core could ...

The discovery that inert helium can form bonds with iron may reshape our understanding of Earth’s history. Researchers from ...

For a long time, scientists thought the Earth's inner core was a solid ball of metal, sort of like a planet within a planet that sits some 3,000 miles (4,828 kilometers) below the surface.

LOS ANGELES — USC scientists have made a groundbreaking discovery about the nature of the Earth’s enigmatic inner core, revealing for the first time that this 1,500-mile-wide ball of iron and ...

Earth’s core could contain helium from the early solar system. The noble gas tucks into gaps in iron crystals under high pressure and temperature.

This is because the internal solar environment plays an important role in determining the weather in space and also the Earth ...

Scientists have raised concerns that the Earth's inner core may completely halt its rotation by 2040, according to a recent paper published in Nature. The study suggests changes are occurring deep ...

They used a laser-heated diamond anvil cell to find this, and the discovery suggests there could be huge amounts of helium in the Earth’s core. This could challenge long-standing ideas about the ...

Scientists found that the inner core’s structure changes as it rotates. It deforms at its border, potentially accumulating more material in some areas and less in others — almost like creating hills ...
