New simulations show carbon enabled Earth’s inner core to solidify under realistic cooling, solving the nucleation paradox.

Scientists looked into decades of seismic wave data and found that it behaved differently in distinct parts of the cores.

A study by researchers at the University of Oxford, University of Leeds, and University College London has identified a new ...

"We found evidence that may indicate a change in the structure of iron, which suggests perhaps two separate cooling events in Earth's history," Stephenson said.

New research reveals that carbon made it possible for Earth’s molten core to freeze into a solid heart, stabilizing the magnetic field that protects our planet. Without it, Earth’s deep interior — and ...

A simple core of pure iron and nickel couldn’t account for the observed properties. The Martian core must be rich in “light ...

Mars is known for its barren desert landscape and dry climate. But two recent studies in the journals Nature and Science go ...

Earth’s core holds key information about Earth’s formation and evolution, and it contributes to massive planetary process such as plate tectonics and geomagnetism. However, understanding this ...

The Earth’s inner core, a solid sphere predominantly composed of iron and nickel, occupies a central role in our planet’s evolution and geodynamo processes. Although hidden beneath thousands ...

Scientists have discovered that Mars has an interior structure similar to Earth's. Results from NASA's InSight mission ...

Our knowledge of what lies beneath Earth's crust has been inferred mostly from what volcanoes have divulged and what seismic waves have whispered. From these indirect observations, scientists have ...
