Earth's inner core, a hot iron ball the size of Pluto, has stopped spinning faster than the planet's surface and might now be rotating slower than it, research suggested on Monday. Roughly 5,000 ...

The inner core was discovered in 1936, and its size (about 20% of Earth's radius) is one of the best-constrained properties of the deep Earth. We use this information to estimate the core's ...

The day is something which appears to be very concrete among all objects in this world. Midnight comes right after 11:59; time moves for 24 hours, and then the process repeats itself. However, the ...

The surface of Earth's inner core may be shape-shifting, new research suggests. The study, published Feb. 10 in the journal Nature, looked at earthquake waves that have skimmed the edge of the inner ...

Tiny changes in Earth’s rotation may reveal a tug-of-war between its deformable inner core, liquid outer core and deep mantle.

Watch a video about how Earth’s inner core changes shape over time, from the University of Southern California. Earth’s inner core is less solid than we once thought Earth’s inner core lies some 3,000 ...

Using seismic waveform data, researchers believe they’ve discovered Earth’s even smaller inner core. The new inner core is made up of about 400 miles of dense iron, the researchers say. Seismic waves ...

Scientists used seismic data discovered Earth's inner core displays a variety of textures that it acquired will it formed from within the fluid outer core. The data set was generated over the past 27 ...
