(CNN) — Deep inside Earth is a solid metal ball that rotates independently of our spinning planet, like a top whirling around inside a bigger top, shrouded in mystery. This inner core has intrigued ...

The blobs lie at the base of Earth’s mantle, around 1,802 miles beneath Africa and the Pacific.

Geophysicist John Vidale noticed something striking while tracking the way seismic waves move from Earth’s crust through its core. The very center of the planet, a solid ball of iron and nickel ...
