A Molten Blizzard Beneath Mercury's Surface
Mercury's magnetic field is about 100 times weaker than that of the Earth - a curiosity that scientists have been trying to make sense of for years. Recent observations of Mercury's rotation suggest that the planet has a partially molten core, and scientists at the University of Illinois and Case Western Reserve University developed laboratory experiments to model what might be happening beneath the surface.
