Earth's Primordial Elements For Life: Study Debunks Meteorite Origin of Key Elements #nasa
New research challenges the longstanding belief that Earth's life-essential elements, like sulfur and nitrogen, arrived via meteorites. Instead, this study, published in Science Advances, suggests these elements, known as volatiles, have been part of Earth since its formation. Focusing on chalcogens (sulfur, selenium, tellurium), the research employed first-principles calculations to analyze isotope behaviors during Earth's formation stages. The findings indicate most volatiles didn't evaporate but remained, contradicting the 'late veneer' theory that posits Earth gained volatiles after its core formation. This revelation not only reshapes our understanding of Earth's history but could also inform the search for habitable exoplanets.
