The internal, infernal machinations of our planet may be way more complex than we suspected. A new, detailed probe of Earth's heart reveals that the rotating inner core doesn't just change in rotation ...

More than 5,000 kilometres beneath us, Earth’s solid metal inner core wasn’t discovered until 1936. Almost a century later, we’re still struggling to answer basic questions about when and how it first ...

The iron atoms that make up the Earth's solid inner core are tightly jammed together by astronomically high pressures—the highest on the planet. But even here, there's space for wiggle room, ...

If the core froze relatively recently, the current thermal state at the inner core–outer core boundary indicates how much the combined core might have been below its melting point when the inner core ...

(CNN) — Deep inside Earth is a solid metal ball that rotates independently of our spinning planet, like a top whirling around inside a bigger top, shrouded in mystery. This inner core has intrigued ...

Despite considerable progress in seismology, mineral physics, geodynamics, paleomagnetism, and mathematical geophysics, Earth’s inner core structure and evolution remain enigmatic. One of the most ...

The solid inner core plays a key role in the deep Earth system. Growth of the inner core is thought to be responsible for the global magnetic field which shields Earth’s surface from harmful solar ...

Back in my day, there were only four layers of Earth: the crust, mantle, liquid outer core and solid inner core. Now, scientists have revealed a new, distinct layer within our planet’s inner core, ...

A model of iron atoms on the move in Earth's inner core. The model demonstrates how iron atoms are expected to move about in the Earth’s inner core over 10 picoseconds.. One picosecond is one ...
