For two decades, scientists have been unable to decide exactly how much heavier elements such as oxygen and carbon — crucial for sustaining life-forms like humans —contribute to the sun’s composition. Marc Pinsonneault, professor of astronomy, comments on a recent discovery that claims the sun has more metal than previously thought by using solar neutrinos to gauge elemental abundances.
