What drove the lunar dynamo? Moon's molten core was likely sustained by alternative power source
New evidence from an ancient lunar rock suggests that the moon once harbored a long-lived dynamo — a molten, convecting core of liquid metal that generated a strong magnetic field 3.7 billion years ago. ...
