“Later on, I’d realize I was staring at evidence the inner core is not solid.” Analyzing the interior of the Earth is tricky business. Without the aid of unobtainium to explore the Earth’s ...

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 ...

That solid iron inner core of Earth may still hold liquid iron, according to a new study from the University of Utah. Scientists have used seismic waves to research Earth’s inner core ...

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. It could help ...

Geochemical evidence from laboratory experiments for a potential solid inner core at the center of Mars is reported in Nature Communications. Deep beneath our feet, at a staggering depth of over 5 ...

The spin of Earth’s inner core may have slowed, with the heart of the planet now rotating at a slightly more sluggish clip than the layers above, new research finds. The slowdown could change ...

These studies revealed that the inner core was a solid ball of iron. However, it may not have the same consistency all the way through, according to a new study from the University of Utah.

Mars may have a solid inner core within its liquid outer core, according to a new analysis of the planet's seismic activity. This could help solve several enigmas about Martian geology – but not ...

“Later on, I’d realize I was staring at evidence the inner core is not solid.” Vidale said that the uncharacteristic properties of one particular dataset from the Canadian station ...
