New research shows Earth’s core contains 90 percent of Earth’s sulfur

So perhaps there is some truth in the old legends of the underworld reeking of brimstone (or sulphur, as it is now called)? New...

Clues to the Earth’s ancient core

Old rocks hold on to their secrets. Now, a geophysicist at Michigan Technological University has unlocked clues trapped in the magnetic signatures of mineral...

Geologists unlock mysteries of the planet’s inner core

Seismic waves are helping scientists to plumb the world's deepest mystery: the planet's inner core. Thanks to a novel application of earthquake-reading technology, a research...

Most of Earth’s carbon may be hidden in the planet’s inner...

As much as two-thirds of Earth's carbon may be hidden in the inner core, making it the planet's largest carbon reservoir, according to a...

Indirect study of Earth’s core

The center of the Earth is about 6,371 kilometers or 4, 000 miles away, roughly the distance between Phoenix and the North Pole. It cannot...

The oldest ice core: Finding a 1.5 million-year record of Earth’s...

How far into the past can ice-core records go? Scientists have now identified regions in Antarctica they say could store information about Earth's climate...

Iron in Earth’s Core Weakens Before Melting

The iron in the Earth's inner core weakens dramatically before it melts, explaining the unusual properties that exist in the moon-sized solid centre of...

Iron Melt Network Helped Grow Earth’s Core, Study Suggests

Stanford scientists recreated the intense pressures and temperatures found deep within Earth, resulting in a discovery that complicates theories of how the planet and...
