White Dwarf StarDIAMONDS ARE FOREVER
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!
Robert Bigelow, any interest?
