For a long time, scientists thought the Earth's inner core was a solid ball of metal, sort of like a planet within a planet ...

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

Now, scientists believe that Earth’s inner core might be less solid than we previously thought. The findings are detailed in a study published February 10 in the journal Nature Geoscience and ...

Until now, the inner core was widely thought of as a solid sphere. The original aim of the USC scientists was to further chart the slowing of the inner core. "But as I was analyzing multiple ...

By Kenneth Chang The inner core at the center of the Earth, a ball of iron and nickel about 1,500 miles wide, may not be perfectly solid. A new study finds evidence that the inner core’s outer ...

Their research led to an unexpected discovery: that inner core is not entirely solid. Scientists from the University of Southern California (USC) analyzed data from earthquakes and identified ...

Until now the inner core was widely thought of as a solid sphere. A new study indicates that the near surface of the inner core may undergo viscous deformation, changing its shape and shifting at ...

The Earth’s inner core is changing shape and may be a little soft on the outside, scientific research suggests. A study ...

Until now the inner core was widely thought of as a solid sphere. The original aim of the USC scientists was to further chart the slowing of the inner core. “But as I was analyzing multiple ...

Previous seismic studies revealed that the inner core is solid metal and rotates within a super-hot molten outer core, also mostly made of metal, including iron and nickel. Researchers have ...

Changes to the inner core has long been a topic of debate for scientists. The post Study claims Earth’s inner core less solid ...
