Today's Spotlight features an illustration, courtesy Hernán Cañellas (provided by Benjamin Weiss), about the lunar dynamo.
New evidence from ancient lunar rocks suggests that an active dynamo once churned within the molten metallic core of the moon, generating a magnetic field that lasted at least 1 billion years longer than previously thought. Dynamos are natural generators of magnetic fields around terrestrial bodies, and are powered by the churning of conducting fluids within many stars and planets.
