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 ...

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 ...

A wealth of new information about Earth’s inner core has surfaced in recent months. Scientists now have evidence that the planet’s innermost layer is changing shape. Scientists who just months ago ...

LOS ANGELES — Scientists have just detected something unusual happening 3,000 miles beneath our feet. New research from an international study reveals that Earth’s inner core, a ball of mostly iron ...

Earth's inner core is undergoing structural transformation. Located 3,000 miles below the Earth's surface, the inner core is anchored by gravity within the molten liquid outer core. Until now the ...

Earth’s core consists of a solid iron-nickel ball rotating within a layer of liquid metal. But that ball may not be as simple as it seems: new research suggests the inner core contains its own inner ...

A Jan. 27 Facebook post (direct link, archive link) draws a connection between the interior of the Earth and modern climate change. "The inner core is spinning differently then (sic) outer Earth and ...
