Hydrogen reserves in Earth’s core large enough to supply at least nine oceans may influence processes on the surface today.

Scientists have long known that Earth's core is mostly made of iron, but the density is not high enough for it to be pure ...

An experiment to quantify the amount of the universe’s lightest element in Earth’s core suggests that the planet’s water has ...

New experiments suggest that Earth’s core may store vast hidden reserves of life-essential hydrogen.

Earth's core contains nine to 45 times more hydrogen than the planet's oceans do, according to a new study that could settle a debate about when and how hydrogen was delivered to Earth.

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, ...

Billions of years ago, Earth was an uninhabitable rock covered in magma. Scientists are still working to decipher the tale of how it transformed into a blue and green orb teeming with life. However, ...

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 ...
