Exploring Earth's deep interior is a far bigger challenge than exploring the solar system. While we have traveled 25 billion km into space, the deepest we have ever gone below our feet is just over 12 km. Consequently, little is known about the conditions at the base of the mantle and the top of the core—the most significant interface in Earth's interior and the region where new research has now uncovered exciting magnetic activity.
