The Zombie Planet at the Center of the Earth
For years, geologists have been searching for an explanation for two strange blobs of Earth's mantle that are denser than the rest. It turns out, they may not be original parts of Earth at all.

This Diagram of Earth Is a Lie
When you learned about the Earth’s interior in school, you were probably shown a diagram that looked like a perfect layer cake. But we've known for a long time that that diagram is... inaccurate at best, and leaves out information that...

6 Mysteries Geologists Can't Solve
There are some geological areas on the planet that scientists still don't understand. For most things it's pretty clear—combine a volcanic eruption a dash of erosion, and boom, you’ve got a striking cliff! But not all the features on...
