Movement of the inner core of our planet has been debated by the scientific community for two decades, with some research indicating that the inner core...
A few decades ago, seismologists identified a thin layer with a lower velocity in Earth’s metallic liquid core. The origin of this layer, known as the...
The rotation of the Earth’s inner core may have recently paused and could be reversing, according to new research by geoscientists from Peking University.

Carbon plays a vital role in geological processes occurring in the Earth’s interior. While most carbon on our planet exists in its core, whether or not...
Each year, about 2 kg of helium-3, a rare isotope of helium gas, escapes from Earth’s interior, mostly along the mid-ocean ridge system. Helium-3 is...
Ultra-low velocity zones sit beneath the central Pacific and Africa, atop the outer core of Earth. In these areas, seismic waves slow by as much as half,...
Terrestrial planets (Mercury, Venus, Earth, and Mars) are differentiated into three layers: a metallic core, a silicate shell (mantle and crust), and a...
Earth’s inner core has an inner core of its own and its distinct properties may point to a dramatic event in the history of our planet, according to...
The inner core of our planet is between 1 and 1.3 billion years old, according to new research led by the University of Texas at Austin and Carnegie Institution...
Changes in the direction of Earth’s internally generated magnetic field may take place 10 times faster than previously thought, according to new research...
In a new study, a team of geophysicists from the University of Maryland, Johns Hopkins University and Tel Aviv University has analyzed echoes of seismic...
The inner core of the Earth is rotating at about 0.05-0.1 degrees per year, according to an analysis of seismic data from repeating earthquakes published...
Earth’s molten core may be leaking heavy isotopes of iron, according to a study led by geoscientists from Aarhus University and the University of California,...
In a new study published in the journal Earth and Planetary Science Letters, a team of researchers from the Scripps Institution of Oceanography at the...
Tiny iron particles fall from Earth’s molten outer core and pile on top of the planet’s solid inner core, according to new research published in the...
Earth’s magnetic field protects and makes our planet habitable by stopping harmful high-energy particles from space, including from the Sun. The source...
New research indicates that nitrogen, one of the most-common elements in the Universe and the dominant gas in the atmosphere of Earth, becomes a metallic...
A team of researchers at the Australian National University in Canberra, Australia, has produced the most comprehensive estimate yet of Earth’s composition...
