Measurements of seismic waves over many years suggest the Earth's core is deformed and reshaped by conditions of extreme heat ...

The surface of Earth's inner core may be shape-shifting, new research suggests. The study, published Feb. 10 in the journal Nature, looked at earthquake waves that have skimmed the edge of the inner ...

The rotation of the Earth's inner core may be reversing, scientists have found in a study that sheds new light on geological processes occurring deep within our planet. The results of the research, ...

Geophysicist John Vidale noticed something striking while tracking the way seismic waves move from Earth’s crust through its core. The very center of the planet, a solid ball of iron and nickel ...

These chemical oddities may explain why Earth seems to be deficient in certain elements — and could prove useful in catalysts ...

Earth's solid inner core has begun to slow its rotation relative to the surface, a shift detected through seismic data. This ...

More than 5,000 kilometres beneath us, Earth’s solid metal inner core wasn’t discovered until 1936. Almost a century later, we’re still struggling to answer basic questions about when and how it first ...

Deep earth may be slowing its roll. Earth’s solid iron inner core appears to be spinning at a slower rate than the planet, according to a new study — but no worries, scientists believe it’s been ...
