Iron 'snow' helps maintain Mercury's magnetic field, scientists say

New scientific evidence suggests that iron snow forms and falls toward the center of Mercury's core, powering its weak magnetic field. This process could be responsible for the planet's mysterious magnetic field, which is about 100 times weaker than Earth's.
