Astronomers Find Diamond Star 4,000 km Wide

Posted by CmdrTaco on from the sharon-osborne-summoned dept.

tclas writes "The cosmic diamond is a chunk of crystallized carbon, 4,000 km across, some 50 light-years from the Earth in the constellation Centaurus. It's the compressed heart of an old star that was once bright like our Sun but has since faded and shrunk. Astronomers have decided to call the star 'Lucy,' after the Beatles song 'Lucy in the Sky with Diamonds.'"

    Except white dwarf interiors will also have lots of oxygen atoms, and the lattice structure (BCC) is different from that of diamonds (interpenetrating FCC). And if you remove the self gravity the white dwarf matter would no longer be crystallized. And this story dates from 2004 - breaking news! Definitely slashdot-worthy ...
