With an estimated 6 sextillion kilograms of the stuff—that’s 21 zeroes by the way—the Earth’s core is another example of why ...

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

A team of researchers has produced the strongest experimental evidence yet that Earth’s iron core holds enormous quantities ...

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

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, ...

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

New potential climate crisis just dropped.

Scientists discovered plate anomalies in Earth's mantle using seismic wave analysis. These mysterious structures challenge tectonic theories.

Climate change is rapidly freshening one of Earth’s saltiest ocean regions in the Southern Indian Ocean, potentially disrupting circulation.

NASA says Earth is about halfway through its lifespan. Scientists explain how solar changes could affect habitability, oceans, and the planet’s future over billions of years ...

For ages, Earth has been known as a blue planet, a vision largely shaped by the vast oceans that cover three-quarters of its surface. But what if this wasn't always the case, and our oceans used to be ...

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