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.

Surprising differences in the two so-called Large Low-Velocity Provinces may risk instability in Earth's protective magnetic ...

The two continent-sized provinces have been known since the 1970s, but it’s only in the last few years we’ve started to ...

Earth appears to be a chill blue planet, but deep down, it’s really a metalhead. Its outer core is mostly molten iron (and ...

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.

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 that sits some 3,000 miles (4,828 kilometers) below the surface.

Why Trust Us? A new study analyzing decades of seismogram data shows that physical changes can occur at the surface of the Earth’s inner core. This means that the surface of the inner core could ...

For decades, scientists have puzzled over traces of primordial helium—a rare isotope known as ³He—escaping from volcanic ...

That is, helium which differs from normal helium, or 4 He, so called because ... implications for understanding Earth’s origins. The presence of helium in the core suggests the young Earth ...

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

The findings confirm that helium could stay locked in Earth's solid inner core for a long time, Olson told Live Science, but he cautioned that only 4% of the core is solid. "This is significant ...
