Universe Observed From A Pale Blue Dot
Diamonds In the Sky
When a star the mass of our Sun uses up its nuclear fuel, it expels most of its outer layers to leave just a very hot core called a white dwarf. Scientists had speculated that at the bottom of a white dwarf’s 31 mile (50 kilometer)-thick crust was crystallized carbon and oxygen, similar to a diamond. And in 2004, they found that a white dwarf near the constellation Centaurus, BPM 37093, was made of crystallized carbon weighing 5 million trillion trillion pounds. In diamond-speak, that’s 10 billion trillion trillion carats!
