Fortunately, Earth has the benefit of a solid inner core and a liquid outer core, both made mostly of iron. This acts as a dynamo that produces a strong magnetic field around the planet.

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

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.

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 ...

Giant regions of the mantle where seismic waves slow down may have formed from subducted ocean crust, a new study finds.

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

A new study presents a compelling new model for the formation of super-Earths and mini-Neptunes -- planets that are 1 to 4 times the size of Earth and among the most common in our galaxy.

After decades of debate, scientists confirm the moon has a solid iron core—mirroring Earth’s inner structure and reshaping how we understand our nearest neighbor. New data and advanced ...

World's Oldest Impact Crater Found, Rewriting Earth's Ancient History Mar. 6, 2025 — Researchers have discovered the world's oldest known meteorite impact crater, which could significantly ...
