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 ...

But this process has been a source of debate amongst scientists for decades. Inner core formation is not just a matter of determining when the core cooled to its freezing point, but instead involves ...

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 ...

An international collaboration including researchers from Lawrence Livermore National Laboratory has discovered that the Earth’s core formed under more oxidizing condition’s than previously proposed.
