By firing tiny projectiles of iron-carbon alloy from a high-speed cannon, scientists have finally demonstrated that a weird ...

Seismic waves passing through the Earth have revealed that the inner core of our planet is now rotating out-of-sync with the layers above it. Update: As reported below, research from January 2023 ...

Geophysicist John Vidale noticed something striking while tracking the way seismic waves move from Earth's crust through its core. The very center of the planet, a solid ball of iron and nickel ...

Deep under the crust and mantle of our Earth lies its core. Earth’s core was formed during the Iron Catastrophe, a major ...

A University of Minnesota professor said the Earth’s inner core hasn’t stopped but has slowed down in response to a CNN article published Jan. 26 titled “Earth’s Core May Have Stopped Turning and ...

Scientists have uncovered new information about the Earth's core: it may not be completely solid. Instead, its center may be more malleable than expected and has changed shape in recent years. These ...

Earth’s solid metal core may no longer be spinning relative to the vast mass of the surrounding planet thanks to what appears to be a recent slowdown, according to the results of a new study. Nestled ...

The Earth's magnetic field and oxygen evolved together over 540 million years, according to a major NASA study.

Earth's inner core may have paused and reversed its spin, a new study suggests. Earthquakes and nuclear blasts can send seismic waves through the mysterious solid-iron core. Those waves hint that the ...

NPR's Ayesha Rascoe talks to John Vidale, professor of earth sciences at the University of Southern California, about new research suggesting the rotation of Earth's inner core may be slowing down.

Earth cross section showing the classic distinction between crust, mantle and core. But new research shows Earth's structure is far more complicated and may change over time. Analyzing an unusual ...
