Earth's Core Leaking: Scientists Uncover the Mystery

Scientists have discovered record concentrations of a helium isotope in 62-million-year-old Arctic rocks, providing evidence of a slow leak in Earth's core. The helium, trapped during the planet's formation, is making its way to the surface. Helium is a rare material on the planet's surface due to its ability to easily diffuse into the atmosphere and space. The high concentration of helium found in volcanic rocks on Canada's Baffin Island suggests its deep and ancient origins. The research suggests that noble gases trapped in Earth's core could have been protected during its formation and gradually seeped into the surrounding mantle over time. This discovery could provide insights into the processes of Earth's core and the formation of planets.
