Primordial Helium-3 May Be Locked in Earth’s Core, Study Finds

Helium-3, an isotope formed during the solar system's birth, may be trapped in Earth's core, a study suggests. Researchers at the University of Tokyo found that helium can mix with iron at extreme heat and pressure, allowing it to remain in Earth's solid core. This discovery could help determine how quickly the planet formed, with a rapid formation timeline explaining...
