Earth’s mysterious core may be leaking: Study

A recent study examining lava flows on Baffin Island in the Arctic Archipelago has found high levels of helium-3 (³He), a rare isotope associated with the Earth’s core. This suggests the possibility that the Earth’s core may be leaking helium-3, challenging the belief that the core and outer layers of the planet are isolated. The discovery implies a greater level of dynamism in the Earth’s deep interior and could reshape our understanding of the planet’s inner workings.
