Back in 2008 a large chunk of rock hurtled into the Earth’s atmosphere. Most of it burned up on the way down, but some fragments of the meteorite landed in the deserts of Sudan. When scientists open up those fragments and examined them under a microscope, they found something very interesting: tiny, tiny, diamonds. Nanodiamonds!

Ten years later, in April 2018, planetary scientists published a paper in Nature arguing that the structure of those nanodiamond crystals could only have come from one place: deep inside a planet — a planet that no longer exists in our Solar System.

Tiny diamonds from space? Planetary destruction? Chris and Emily are totally up for that.
