Hydrogen from geological formations makes up about 10% of the flammable gases that form the Yanartaş flames near Cirali, ...

Earth’s core could contain helium from the early solar system. The noble gas tucks into gaps in iron crystals under high pressure and temperature.

The discovery that inert helium can form bonds with iron may reshape our understanding of Earth’s history. Researchers from ...

These results suggest that similar reactions between helium and iron may have occurred within Earth’s core shortly after its formation, trapping much of the primordial helium-3 in the material that ...

An international team led by researchers in Japan and Europe has discovered a new multi-planet system around a Sun-like star, ...

Scientists have uncovered surprising evidence that helium, a gas long thought to be chemically inert, may actually bond with ...

New research reveals that the Moon's core has a density similar to that of iron. This discovery may resolve long-standing ...

The discovery that helium and iron can mix at the temperatures and pressures found at the center of Earth could settle a long-standing debate over how our planet formed.

Scientists have identified another possible commonality between Earth and Mars: a solid inner core. Scientists have ...

A rare isotope from the early solar system may be locked in Earth's core, revealing insights into planetary formation ...

Earth's innermost layer is called the core. The outside of Earth's core is made from molten nickel and iron that can reach temperatures of 9,000 degrees Fahrenheit (5,000 degrees Celsius).

Deep within Earth’s mantle lie two enormous, continent-sized structures known as LLVPs. Scientists once believed these ...
