Mercurys Diamond Layer Insights: study points to deep sparkling core; findings may explain odd magnetic field

Mercury, once thought a simple iron ball, may boast a mile-thick diamond layer beneath its surface. New research suggests intense pressure and sulfur during its cooling transformed carbon into diamond, forming a unique boundary between its core and mantle. This discovery could explain the planet's strong magnetic field and offers clues for finding habitable exoplanets.
