Key Takeaways on Earth's Inner Core Earth's inner core is solid and blistering hot. For decades, scientists have known ...

Two Australian scientists argue in a new paper that within the Earth’s core, based on measurements of waves reverberating along the Earth’s diameter, is an innermost inner core, about 800 ...

Earth's surprise inside: Geologists unlock mysteries of the planet's inner core Date: February 9, 2015 Source: University of Illinois at Urbana-Champaign ...

He and his colleagues found the inner core creates a "superionic state" made up of hydrogen, oxygen and carbon. He said it's unlike any solid or liquid form.

The inner core is about 9,400 F (5,200 C) — about as hot as the surface of the sun — but tremendous pressure keeps it mostly solid. Inside the inner core is the innermost core, a 450-mile-wide ...

The mapping shows there isn’t a homogeneous inner core, but one that has evolved differently in various spots. The team believes that this shows the trapping of liquid iron inside the solid core.

New research may have finally figured out what is inside the Moon, and it has scientists excited to dig deeper.

The inner core, spanning about 760 miles in diameter, primarily consists of iron and nickel. Despite extreme temperatures, the inner core remains solid due to immense pressure at its center.

While this new layer is difficult to observe, its existence may point to an unknown, dramatic event in Earth's history. Investigating the structure of the inner core can help us understand more ...

It is true that the outer core generates electrical currents that sustain the planet’s magnetic field, but Vidale says shifts in the Texas-size inner core are too minuscule to have an impact.

The inner core has slowed so much that it has essentially kicked into ... Another player in the endless tug-of-war taking place inside the planet is the lower level of the planet's mantle, ...
