Sunken Continents Near Earth's Core Could Unbalance Our Magnetic Field

Continent-sized structures of mineral protruding from the lower mantle towards Earth's outer core may be contributing to an instability of our planet's magnetic field.

Centre of the Earth could hold large reservoir of iron-helium compounds

In the new work, Hirose and colleagues at other institutions in Japan and Taiwan propose that the iron core of the Earth formed bonds with helium, allowing the core to act as a reservoir. 

Earth's Inner Core Is Mysteriously Changing Shape, Study Reveals

The internal, infernal machinations of our planet may be way more complex than we suspected.

Something in Earth's Core May Be Altering The Length of Days

A team of Swiss geophysicists thinks they have found the answer in Earth's molten iron core which causes tiny alterations affecting the planet's rotation.

Earth's inner core is slowing down, making our days a bit longer

Deep beneath our feet, in the heart of our planet, something unexpected is happening. Scientists have discovered that Earth’s inner core, a solid iron-nickel sphere roughly the size of the moon, is slowing down.

Life Blossomed When Earth's Magnetic Field Nearly Collapsed 590 Million Years Ago

Earth's magnetic field nearly collapsed some 590 million years ago, presumably putting life on the planet's surface at risk of a rise in cosmic radiation.

Ancient Rocks Reveal Earth's Magnetic Field Existed 3.7 Billion Years Ago

Rocks that formed some 3.7 billion years ago in the early Archean have given us the earliest glimpse yet of Earth's magnetic field.

Earth's Core Seems to Mysteriously Wobble Every 8.5 Years

A team led by geoscientists Yachong An and Hao Ding of Wuhan University have determined that Earth's inner core wobbles with a periodicity of 8.5 years.

Earth's Magnetic Field Could Be on The Verge of Flipping Over

The location of the north magnetic pole has moved by about 965 kilometers since the first measurement was taken in 1831. This could indicate the beginning of a field reversal, but scientists really can’t tell with less than 200 years of data.

Earth's Core Is Changing

Water from Earth's surface can find its way deep into the planet, and new research explains how it changes the outermost region of the metallic liquid core.

Scientists discover alien planet debris buried deep under Earth's crust

Long ago, an alien planet crashed into Earth – causing a collision so big the debris formed the Moon and left mysterious remnants lodged deep in the Earth’s mantle.

Earth's core could be leaking helium

Record concentrations of a helium isotope found inside 62-million-year-old Arctic rocks could be the most compelling evidence to date of a slow leak in our planet's core.

Iron Atoms Discovered on the Move in Earth's Solid Inner Core

An international study found that certain groupings of iron atoms in the Earth’s inner core are able to move about rapidly, changing their places in a split second while maintaining the underlying metallic structure of the iron.

Earth's Core Appears to Be Wrapped in an Ancient, Unexpected Structure

The most high-resolution map yet reveals something we previously never knew about: an ancient ocean floor that may wrap around the core. This thin but dense layer exists around 2,900 kilometers below the surface.

Beneath the Earth, ancient ocean floor likely surrounds the core

U.S. recent study revealed a layer between the Earth's core and the mantle that is likely a dense, yet thin, sunk ocean floor.
