Deep within Earth’s core, scientists are uncovering signs of a hidden structure that challenges long-standing models of the planet’s interior.

Two new seismic studies suggest Earth's core is more complex than previously thought, revealing both a possible 'innermost inner core' and widespread ultralow velocity zones along the core-mantle ...

Researchers are still discovering more about the Earth's center. A team at Australian National University (ANU) has found evidence of a new layer to the planet sitting within the inner core. This ...

An earthquake originating from Alaska caused seismic waves to penetrate the innermost inner core of the Earth. (Credit: Drew Whitehouse, Son Phạm and Hrvoje Tkalčic) Planet Earth is a marvelous ...

Prefer Newsweek on Google to see more of our trusted coverage when you search. Earth's inner layers have just got a bit more complicated, with scientists discovering a whole new inner core within the ...

Researchers have found evidence for a distinct 'innermost inner core' at the center of Earth, challenging the long-held four-layer model of the planet’s structure. Seismic wave analysis reveals a ...

For generations, scientists have probed the structure and composition of the planet using seismic wave studies. This consists of measuring shock waves caused by earthquakes as they penetrate and pass ...

A group of scientists has discovered a hidden layer of molten rock under the Earth's surface. The new layer is located around 100 miles beneath the surface and appears to extend below much of the ...

Data captured from seismic waves caused by earthquakes has shed new light on the deepest parts of Earth's inner core, according to seismologists. Data captured from seismic waves caused by earthquakes ...

The heart of our planet has been spinning unusually slowly for the past 14 years, new research confirms. And if this mysterious trend continues, it could potentially lengthen Earth's days — though the ...
