Scientists detect unexpected widespread structures near Earth’s core

University of Maryland geophysicists analyzed thousands of recordings of seismic waves, sound waves traveling through the Earth, to identify echoes from the boundary between...

Growing mountains or shifting ground: What is going on in Earth’s...

Exhaustive seismic data from repeating earthquakes and new data-processing methods have yielded the best evidence yet that the Earth's inner core is rotating --...

Heavy iron isotopes leaking from Earth’s core

Earth’s molten core may be leaking iron, according to researchers who analyzed how iron behaves inside our planet. The boundary between the liquid iron core...

Is the Earth’s inner core oscillating and translating anomalously?

A theoretical mineral physics approach based on the ab initio methods was adopted to determine the viscosity of hexagonal, close-packed iron at the extreme...

Scientists Find Iron ‘Snow’ in Earth’s Core

The Earth's inner core is hot, under immense pressure and snow-capped, according to new research that could help scientists better understand forces that affect...

Mercury has a solid inner core

Mercury Have Metallic Cores Scientists have long known that Earth and Mercury have metallic cores. Like Earth, Mercury's outer core is composed of liquid metal,...

Scientists go to extremes to reveal make-up of Earth’s core

Experiments conducted at extreme conditions are giving scientists new insights into the chemical make-up of the Earth's core. Advanced laboratory techniques reveal that our planet's...

Researchers confirm Earth’s inner core is solid

A new study by researchers at The Australian National University (ANU) could help us understand how our planet was formed. Associate Professor Hrvoje Tkalčić and...

Sound waves reveal enormous diamond cache deep in Earth’s interior

There may be more than a quadrillion tons of diamond hidden in the Earth's interior, according to a new study from MIT and other...

Laser experiments lend insight into metal core at heart of Earth

Scientists have discovered fresh insights into the metallic core at the centre of our planet. The findings could aid understanding of how Earth was formed...

Seismologists use massive earthquakes to unlock secrets of the outer core

By applying new data and Princeton's supercomputers to the classic question of what lies beneath our feet, Princeton seismologist Jessica Irving and an international...

New insight into Earth’s crust, mantle and outer core interactions

A new study by the University of Liverpool, in collaboration with the Universities of Lancaster and Oslo, sheds light on a longstanding question that...

Ultrahigh-pressure laser experiments shed light on super-Earth cores

Using high-powered laser beams, researchers have simulated conditions inside a planet three times as large as Earth. Scientists have identified more than 2,000 of these...

Do you know where your xenon is?

The paradox of the missing xenon might sound like the title of the latest airport thriller, but it's actually a problem that's stumped geophysicists...

Challenging core belief: Have we misunderstood how Earth’s solid center formed?

It is widely accepted that the Earth's inner core formed about a billion years ago when a solid, super-hot iron nugget spontaneously began to...

Earth’s core and mantle separated in a disorderly fashion

Plumes of hot rock surging upward from the Earth's mantle at volcanic hotspots contain evidence that the Earth's formative years may have been even...

Trickle-down is the solution (to the planetary core formation problem)

Scientists have long pondered how rocky bodies in the solar system -- including our own Earth -- got their metal cores. According to research...

Plume-subduction interaction forms large auriferous provinces

Gold enrichment at the crustal or mantle source has been proposed as a key ingredient in the production of giant gold deposits and districts....

Study sheds new light on earth’s evolution

Research from the University of Texas at Arlington and the Wadia Institute of Himalayan Geology suggests that hydrogen, oxygen, water and carbon dioxide are...
