The length of Earth’s day drifts by a few milliseconds over decades, and a Nature paper from the University of Alberta argues ...

Earth's rotation experiences slight variations in day length due to interactions within its inner core and mantle. Researchers have developed a model revealing how gravitational forces drive these ...

The Earth does not hide a proven “second core“, but seismological data show that its interior is much more complex than the ...

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 ...

While fluctuations in day length were linked to the liquid outer core, new research identifies the solid inner core's ...

This artist’s concept of the Earth’s core shows the inner core in red, the outer core in blue, and the donut in red. The donut region contains more light elements around the equator. Image via ...

The new map highlights six regions that had been poorly sampled by PKP precursor studies and now appear to be promising ...

A recent study revealed that Earth’s inner core is slowing down, prompting scientists to investigate further. Their research led to an unexpected discovery: that inner core is not entirely solid.

What’s the News: In geologists’ traditional view of the middle of the Earth, the solid inner core is gradually growing as more of the liquid core freezes, as the planet continues its billions-of-years ...
