The blue ice giants in our outer solar system have unusual magnetic fields, missing what we understand as traditional north-south poles. For decades, scientists have been trying to understand why while also puzzling out what the planets are made of under their atmospheres. Some have suggested the planets may experience diamond rain others that their mantles consist of a mix of slushy water and ammonia. A new study has suggested the planets’ have layered interiors that generate their magnetic fields. The secret lives of ice giants are the focus of this episode of Stats and Stories.
