New simulations show carbon enabled Earth’s inner core to solidify under realistic cooling, solving the nucleation paradox.

For four years, a lone robot sat on the dusty plains of Mars, listening. The InSight lander, a three-legged marvel of ...

Researchers have made a surprising discovery that offers clues to how the Earth’s core formed millions of years ago.

These findings may explain why some experimental evidence has been inconsistent with our current models of Earth's structure.

For more than 100 years, scientists have puzzled over whether the Earth’s magnetic field had already been generated stably back in its early days when its inner core was fully liquid &ndash ...

NASA scientists have uncovered an unexpected presence inside Mars, a solid mass around 373 miles in size. This finding has ...

The inner core contradiction 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 ...

A lost chapter in our planet's history.While some models suggest the material of the inner core channels seismic waves faster parallel to the equator, others indicate the mix of materials allows ...
