With an equatorial diameter of 7926 miles (12,760 kilometers), our planet Earth is the biggest of the terrestrial planets and ...

Researchers studying decades of earthquake data say they have found the first evidence that, in addition to spinning backward ...

Not only is Earth’s inner core spinning and growing, but it’s also changing shape, according to new research. Our planet’s [… ...

Seismic wave data previously suggested the Earth’s hot inner core is slowing its spin. Now, researchers say it’s also ...

But it also opens new questions about how changes in the core could affect the length of our 24-hour day, Earth’s magnetic ...

A new study out this week said that the Earth's inner core is less solid than previously thought. Scientists still have ...

Scientists of course cannot cut into Earth and directly observe its insides. Instead, their knowledge is inferred from the ...

Scientists at the National Physical Laboratory in England recorded the shortest day ever on June 29 and another shortened day on July 26, according to Popular Mechanics, a science and technology ...

A new study in Nature Geoscience reveals insights about the Earth’s core. While we often learn about the inner and outer ...

Scientists found that the inner core’s structure changes as it rotates. It deforms at its border, potentially accumulating ...

Research suggests Earth’s inner core, a metal sphere within the molten outer core, is slowing its spin and reshaping. Seismic wave analyses from earthquakes reveal discrepancies indicating ...

Earth’s core is located below the middle layer called the mantle and the outer layer –or crust. It consists of two main parts ...
