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.

The movements within Earth’s molten core have been resisting efforts to understand them for a long time, but agreement ...

The Earth's core affects humans by producing its magnetic field, which protects life from dangerous radiation from the sun, allowing life to flourish on Earth.

The Earth’s core is not literally stopping; however it is changing. The Earth is not a solid ball; it consists of several layers . There is the innermost core, which is a solid sphere about the ...

The inner core, which was discovered in 1936 by Danish seismologist Inge Lehmann, makes up less than 1 percent of Earth’s volume (Earth’s center is located about 4,000 miles below the surface).

The 2003 disaster film “The Core” imagines that the rotation of Earth’s center has stalled, damaging the magnetic field that envelops the planet — and triggering a violent lightning storm ...

Earth's core has been a growing topic of interest. It is responsible for the planet's magnetic field, which protects life from the sun's radiation. Despite its importance, ...

The movements within Earth’s molten core have been resisting efforts to understand them for a long time, but agreement between a mathematical and physical model has led two physicists to claim ...
