Using a laser-heated diamond anvil cell, they exposed iron and helium to pressures between 5 and 55 gigapascals—50,000 to 550,000 times atmospheric pressure—and temperatures ranging from 1,000 ...

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.

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 ...

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, ...

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 ...

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.

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 ...
