Is Earth's inner core solid or liquid? While the inner core is extremely hot, experts have known that it is solid for many ...

Australian geologists have added to the growing pool of research supporting the existence of a distinct innermost inner core.

Luckily, mineral physics is bringing us closer to solving the mystery. The inner core is responsible for Earth's magnetic field, which acts like a shield, protecting us from harmful solar radiation.

The rotation of the Earth's inner core may be reversing, scientists have found in a study that sheds new light on geological processes occurring deep within our planet.

A new study confirms that Earth's inner core has been rotating more slowly than usual since 2010. This mysterious "backtracking" could also end up slightly altering the planet's overall rotation ...

Earth's inner core is undergoing structural transformation. Located 3,000 miles below the Earth's surface, the inner core is anchored by gravity within the molten liquid outer core. Until now the ...

Shaking from large earthquakes provides hints about something different at the center of the planet. By Kenneth Chang The inner core of the Earth appears to hold an innermost secret. Geology ...

A new study of decades worth of seismogram data shows that the surface of Earth’s iron and nickel core is more malleable than scientists thought.

Earth's Core Keeps Getting Weirder A recent study found that our planet's inner core is a mosaic of textures and densities, and maybe some trapped molten metal.

Earth’s inner core is surprisingly soft, and wiggling iron atoms may help explain why. The innermost part of our planet is a solid iron ball smaller than the moon and almost as hot as the ...

Luckily, mineral physics is bringing us closer to solving the mystery. The inner core is responsible for Earth’s magnetic field, which acts like a shield, protecting us from harmful solar radiation.

Imagine Earth’s inner core — the dense center of our planet — as a heavy, metal ballerina. This iron-rich dancer is capable of pirouetting at ever-changing speeds. That core may be on the ...
