But an experiment revealed it may be a lot softer — more like butter, a lead scientist said. It could help explain why Earth's magnetic field is so weird. A new study challenges the long-held ...

More than 5,000 kilometers 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 ...

Researchers have been aware for a few years that our inner core may not be the simple, solid ball of metal that we believed it to be. Seismic waves have illuminated that the core doesn’t appear to be ...

More than 5,000 kilometers 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 ...

The core of the Earth may not be as solid as scientists had previously thought, according to new research that suggests some of it may actually be a white-hot mush. The center of the Earth may lie ...

Earth’s inner core may be made of fluid light elements swirling around amid a solid lattice of iron, according to a computer simulation study. A team of physicists recently modeled how alloys of iron ...

Scientists have long wondered what lies at the very center of the Earth, and the latest research is putting weight behind a theory that our planet has a distinct ball of iron within its metallic core.

A team of geologists from China and the US have found evidence to suggest that snow may be falling within the broiling hot core of planet Earth. Of course, this isn’t your everyday surface snow – the ...

The distance from the Earth's surface to its center is almost 4,000 miles—but our planet's structure is not uniform and is actually made up of several different layers, some of which are hotter than ...
