Because scientists can't actually see the center of the Earth, they used data from seismic waves created by earthquakes to analyze its composition. "They found the innermost inner core changed the ...

Scientists have uncovered new information about the Earth's core: it may not be completely solid. Instead, its center may be more malleable than expected and has changed shape in recent years.

the surface of the Earth’s inner core may be changing, as shown by USC scientists that detected structural changes near the planet’s center. The original aim of the USC scientists was to ...

The discovery that helium and iron can mix at the temperatures and pressures found at the center of Earth could settle a long-standing debate over how our planet formed.

The discovery that inert helium can form bonds with iron may reshape our understanding of Earth’s history. Researchers from ...

Our study of the Earth’s core has advanced quite a bit ... waves of earthquakes as they passed through the planet’s center. The study says that this helped them detect the Earth’s true ...

At the center of the Earth lies a hot, solid inner core composed predominantly of nickel and iron, with a radius of approximately 1,200 to 1,300 kilometers. This inner core is surrounded by a ...

Figuring out how helium-3 got incorporated into the core during Earth's formation is very important for understanding when the planet formed, Olson said. Light gases like helium hung around in the ...
