Deep beneath the Earth's surface, the inner core has long been thought of as a solid sphere, steadily growing as the outer core cools and crystallizes. However, a new study suggests that the inner ...

It was actually this change in rotation which Professor Vidale had set out to study when he made his shocking discovery. The researchers gathered 168 pairs of repeating earthquakes from 42 ...

The study has centered on a type of star known as a Delta Scuti, whose mass ranges between 1.5 and 2.5 times that of the Sun and that rotates so fast that it can be deformed — instead of being ...

By analyzing seismic records from 121 earthquakes originating near the South Sandwich Islands between 1991 and 2024, researchers were able to track how the inner core's rotation speeds up and ...

Spinning planets bulge at their equator and solid surfaces deform differently than liquid sea surfaces. As a result, surface topography of the shorelines deformed as the planet’s rotation axis ...
