Laboratory experiments conducted under extreme pressure indicate that hydrogen entered the Earth’s core together with silicon and oxygen during its formation. This indicates that the Earth’s core may ...

New research has identified a new restriction on the chemistry involved in the Earth’s core, explaining how it was able to crystallize millions of years ago. According to this work, the core would ...

Researchers have long struggled to explain how Earth’s solid inner core formed, cooled, and crystallized without undergoing extreme supercooling. But a recent study published in Nature ...

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 ...
