Taking Earth’s inner temperature

The temperature of Earth's interior affects everything from the movement of tectonic plates to the formation of the planet. A new study led by Woods...

‘Quartz’ crystals at Earth’s core power its magnetic field

The Earth's core consists mostly of a huge ball of liquid metal lying at 3000 km beneath its surface, surrounded by a mantle of...

New theory explains how Earth’s inner core remains solid despite extreme...

Even though it is hotter than the surface of the Sun, the crystallized iron core of Earth remains solid. A new study from KTH...

Earth’s water may have originally been formed deep within its mantle,...

Earth's water may have originally been formed by chemical reactions deep within the planet's mantle, according to research led by University College Dublin. The new...

Research journey to the center of the Earth

Researchers in Japan say they may be one step closer to solving the mystery at the core of Earth. It has long been established that...

Heat from earth’s core could be underlying force in plate tectonics

For decades, scientists have theorized that the movement of Earth's tectonic plates is driven largely by negative buoyancy created as they cool. New research,...

Satellites help discover a jet stream in the Earth’s core

A jet stream within the Earth's molten iron core has been discovered by scientists using the latest satellite data that helps create an 'x-ray'...

Targeting mysteries of deep Earth

A mineral far below Earth's surface may hold the key to how much water is stored in the planet, a Florida State University researcher...

Seismic ‘CT scans’ reveal deep earth dynamics

A new look 100 miles beneath a massive tectonic plate as it dives under North America has helped clarify the subduction process that generates...

How hot is too hot for Earth-style life?

Mission seeks to answer key questions: How deep is Earth's habitable zone? How deep is the deep subseafloor biosphere? How does the deep biosphere...

Probing giant planets’ dark hydrogen

Hydrogen is the most-abundant element in the universe. It's also the simplest--sporting only a single electron in each atom. But that simplicity is deceptive,...

Found: Surviving evidence of Earth’s formative years

New work from a team including Carnegie's Hanika Rizo and Richard Carlson, as well as Richard Walker from the University of Maryland, has found...

How the spectacular Hawaiian-Emperor seamount chain became so bendy

The physical mechanism causing the unique, sharp bend in the Hawaiian-Emperor seamount chain has been uncovered in a collaboration between the University of Sydney...

Map of flow within the Earth’s mantle finds the surface moving...

Researchers have compiled the first global set of observations of the movement of the Earth's mantle, the 3000-kilometre-thick layer of hot silicate rocks between...

Geochemical detectives use lab mimicry to look back in time

New work from a research team led by Carnegie's Anat Shahar contains some unexpected findings about iron chemistry under high-pressure conditions, such as those...

‘Forbidden’ substances on super-Earths

Using mathematical models, scientists have 'looked' into the interior of super-Earths and discovered that they may contain compounds that are forbidden by the classical...

The days are getting longer: Rotation of Earth’s core holds a...

Scientists are studying past changes in sea level in order to make accurate future predictions of this consequence of climate change, and they're looking...

Liquid acoustics half way to the Earth’s core

The most direct information about the interior of the earth comes from measuring how seismic acoustic waves—such as those created by earthquakes—travel through the...

How we discovered that the Earth’s inner core is older than...

According to recent estimates, the Earth's solid inner core started forming between half a billion and one billion years ago. However, our new measurements...

Earth’s inner core was formed 1-1.5 billion years ago

There have been many estimates for when the earth's inner core was formed, but scientists from the University of Liverpool have used new data...
