British energy company Space Solar announced it successfully tested an in-space assembly method for its upcoming satellites.

"If the effect is real and scaling behaves the way our equations say, then the possibility becomes real," Chyba told Newsweek ...

In 2009-2010, the rotation of the Earth's inner core completely stopped. After such events, the inner core is expected to resume rotation, presumably in the same direction as the Earth itself.

In other words, the rotation and shape of the core in that outer layer interact with the Earth’s other layers, which explains why differences are picked up by different seismic recorders.

The study, “Annual-scale variability in both the rotation rate and near surface of Earth’s inner core,” was published in Nature Geoscience on February 10, 2025, by researchers from the ...

Changes in the inner core’s rotation can also affect the length of our day. “Ideally, we’d like to tie all these things that we’re seeing together” to make deep Earth less mysterious ...

Earth’s Inner Core Has Warped Over the Past Two Decades, Scientists Say The rotation speed and shape of Earth's deepest layer has been experiencing some surprising changes.

Those changes in rotation are mainly due to magnetic forces generated by convection in Earth’s liquid outer core, says John Vidale at the University of Southern California. “That flow is ...

Melting ice is slowing Earth's spin and causing changes to its axis, new studies find. The shifts are causing feedback beneath the surface, impacting the planet's molten core.
