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...

Scientists produce best estimate of Earth’s composition

Scientists at ANU have produced the best estimate of Earth's elemental composition which will help them understand how the Earth formed 4.6 billion years...

Lunar dynamo’s lifetime extended by at least 1 billion years

New evidence from ancient lunar rocks suggests that an active dynamo once churned within the molten metallic core of the moon, generating a magnetic...

Scientists shed light on carbon’s descent into the deep Earth

Examining conditions within the Earth's interior is crucial not only to give us a window back to Earth's history but also to understand the...

Quantum mechanics inside Earth’s core

Without a magnetic field life on Earth would be rather uncomfortable: Cosmic particles would pass through our atmosphere in large quantities and damage the...

Earth’s first example of recycling – its own crust!

Rock samples from northeastern Canada retain chemical signals that help explain what Earth's crust was like more than 4 billion years ago, reveals new...

20 Things You Didn’t Know About “Inner Earth”

1. In 1692 Edmond Halley (of comet fame) proposed that the Earth is hollow. Below the outer crust where we live, he pictured two...

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,...
