By firing tiny projectiles of iron-carbon alloy from a high-speed cannon, scientists have finally demonstrated that a weird ...

Scientists have discovered that Earth’s inner core may not be fully solid. A rare “superionic” state of matter could explain ...

The iron-rich core at the center of our planet has been a crucial part of Earth's evolution. The core not only powers the magnetic field which shields our atmosphere and oceans from solar radiation, ...

Earth’s inner core has long puzzled scientists because seismic waves move through it unevenly. Compressional waves from ...

The solid inner core at the center of the Earth, surrounded by the outer core, mantle and crust. Here’s why: While it is well known that a material must be at or below its freezing temperature to be ...

Deep under the crust and mantle of our Earth lies its core. Earth’s core was formed during the Iron Catastrophe, a major ...

The discovery that helium and iron can mix at the temperatures and pressures found at the center of Earth could settle a long-standing debate over how our planet formed. When you purchase through ...

Earth's core cannot be made just of iron — it also appears to contain carbon. And our research suggests it may contain a bit of oxygen and possibly silicon as well. When you purchase through links on ...
