Forget a doomsday asteroid or melting permafrost. It’s the freezing of Earth’s core that will end the world in today’s ...

This superionic state of matter would neatly explain some unusual behavior in the core, such as the way it slows certain waves, and measurements that suggest it's squishy like butter rather than rigid ...

New research suggests that the Earth's solid inner core is softer and more dynamic than previously thought, changing ideas.

Earth’s inner core has long challenged researchers because seismic waves do not move through it uniformly. Compressional waves generated by earthquakes travel roughly 3 to 4 percent faster along Earth ...

Earth’s deep interior may hold water equal to today’s oceans, challenging long-held views of how the planet became habitable.

Long-term satellite measurements show that Earth’s magnetic field is changing faster and more unevenly than expected, driven ...

Earth's core cannot be made just of iron — it also appears to contain carbon. And our research suggests it may contain a bit of oxygen and possibly silicon as well. When you purchase through links on ...

Two enormous structures that sit at the border between the Earth’s mantle and its core have puzzled scientists for decades, defying reigning theories of how our planet came to be. In a new study ...

Researchers at Göttingen University have uncovered new evidence that some of Earth’s most precious metals began their journey far deeper than once thought. Working with volcanic rocks from ocean ...
