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 ...

Earth's inner core, a hot iron ball the size of Pluto, has stopped spinning in the same direction as the rest of the planet and might even be rotating the other way, research suggested on Monday.

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 ...

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 ...

The wheel of time isn’t turning like it used to. Scientists have discovered that our planet’s core has been rotating at a slower rate for nearly 15 years — and it could mean longer days for some. The ...

The iron-rich core at the center of our planet has been a crucial part of Earth's evolution. The core not only powers the magnetic field which shields our atmosphere and oceans from solar radiation, ...

The core of the Earth has remained a mystery to researchers for quite some time, and for one simple reason, we can't drill down to the core to collect a sample. Some of the most basic questions, such ...

Scientists have peered into the Earth's inner core and are surprised at what they found. The Earth's core is the dense center of the planet that burns at 9,392 degrees Fahrenheit. Without it, life on ...

A new study confirms that Earth's inner core has been rotating more slowly than usual since 2010. This mysterious "backtracking" could also end up slightly altering the planet's overall rotation, ...
