The inner core is made of solid iron-nickel about 3,000 miles below the surface of the Earth. Scientists believe that the inner core’s rotation began to slow down in 2010 , but what that really ...

Analyzing the interior of the Earth is tricky business. Without the aid of unobtainium to explore the Earth’s depths (a la 2003’s The Core), scientists instead have to rely on seismograms that ...

The liquid outer core, which extends to 1,795 miles above the solid core, Koper says, produces a protective field of magnetic energy. The molten metal cools as it approaches Earth’s rocky mantle ...

The planet’s solid inner core might rotate at a different rate than the rest of the planet, and that rate might be changing. Skip to main content. Scientific American. January 25, 2023.

The Earth's inner core is an enduring mystery: Here's how researchers are starting to solve it. Deep beneath our feet, at a staggering depth of over 5,100km, lies Earth's inner core—a solid ball ...

The Earth’s inner core is incredibly tricky to study, since it’s buried beneath thousands of miles of rock. New seismic studies suggest that it’s not just a solid ball of iron, as has been ...

Scientists have long thought Earth's inner core is like a huge solid metal ball. But an experiment revealed it may be a lot softer — more like butter, a lead scientist said.

On Earth, the solid inner core drives convection in the liquid outer core, which generates the planet’s magnetic field. If Mars has a similar core structure, why doesn’t it have a similar field?.

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.
