Earth's inner core, once rotating faster than the surface, has begun to slow, impacting day length by fractions of a second. This subtle shift, detected through seismic wave analysis, reveals complex ...

The solid inner core at the center of the Earth, surrounded by the outer core, mantle and crust. Here’s why: While it is well known that a material must be at or below its freezing temperature to be ...

Earth's solid inner core has begun to slow its rotation relative to the surface, a shift detected through seismic data. This ...

The iron-rich core at the center of our planet has been a crucial part of Earth's evolution. The core not only powers the magnetic field which shields our atmosphere and oceans from solar radiation, ...

An analysis of seismic waves propagating through Mars finds evidence that the planet has a small, solid inner core, which challenges existing planetary models. Read the paper: Seismic detection of a ...
