Earth’s core has often been described as just a giant ball of iron and nickel. Now, a new study argues that it is also a ...

As much as 45 oceans’ worth of hydrogen may be in Earth’s core, scientists reported, suggesting most of Earth’s water was ...

The volume of the ocean, its average purity, and the chemical makeup of H₂O allow a simple estimate of the amount of hydrogen ...

A new scientific revelation reveals that deep in the Earth’s core lies a good amount of hydrogen as well as a large amount of iron. While the iron in the core has always been recognized as dominant, ...

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 ...

Precious metals may be escaping from the planet’s core. This hotly debated subject could help us understand Earth’s evolution and determine whether life exists elsewhere in the Universe ...

Earth’s core dynamics and conductivity underpin the generation and evolution of the geomagnetic field, influencing the thermal history and long‐term sustainability of the geodynamo. Studies over ...

The Earth’s inner core, a solid sphere predominantly composed of iron and nickel, occupies a central role in our planet’s evolution and geodynamo processes. Although hidden beneath thousands of ...

Scientists suggest that huge reserves of hydrogen inside the Earth may have been key in the formation of water.

The Earth's magnetic field and oxygen evolved together over 540 million years, according to a major NASA study.

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 ...
