Helium gas may be seeping from Earth’s core, say scientists who found extremely high helium isotope ratios in lavas on Baffin Island. Skip to main content. Scientific American.

If helium is present at these depths, it could serve as a major reservoir of primordial gas, altering our understanding of Earth's internal composition and the mechanisms driving volcanic activity.

Researchers now appreciate that gas planets are more complex than first thought. New findings have implications for our ...

While helium-4 is common on Earth, helium-3 is more readily found elsewhere in the cosmos, which is why scientists were surprised to detect a larger amount of the element than had been previously ...

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.

Now that helium has become a scarce commodity on Earth, some experts think it may be time to head to the Moon to suss some out and bring it back. Seattle-based Interlune recently surprised much of ...

Given the high ratio of 3 He/ 4 He, which was found in volcanic rocks, has long been believed by researchers to be deep in the Earth’s mantle are primary materials containing helium-3 However, ...

Ancient helium that became trapped in Earth’s core when our planet formed billions of years ago may be leaking from lava flows, according to researchers. Earth’s core is leaking, scientists ...

Like a saggy balloon, Earth's core is leaking helium, a new analysis finds The study has interesting implications for how our planet formed and what's up with our mysterious core ...
