Scientists have seemingly settled long-standing arguments about whether the components of Earth originated from the inner or ...

Deep within Earth’s core, scientists are uncovering signs of a hidden structure that challenges long-standing models of the planet’s interior.

Earth's inner core, the solid iron-rich mass at the center of our planet, is slowly growing as the surrounding molten outer core cools and freezes. But this process has been a source of debate amongst ...

Planetary scientists led by Paolo Sossi have determined that Earth assembled almost entirely from material originating in the inner solar system, with outer solar system contributions limited to just ...

Planetary scientists have long debated where the material that formed Earth comes from. Despite its location in the inner solar system, they consider it likely that 6–40% of this material must have ...

Deep beneath our feet, far beyond the reach of drills or submersibles, Earth hides a solid metal heart that behaves in ways geophysicists have struggled to explain. New experiments now suggest that a ...

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 ...

The iron-rich core at the centre 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, ...
