A Diamond the Size of the Earth?

 What? From Gagadget:

The white dwarf is located 104 light years from our planet. The star is believed to have been around for 4.2 billion years, but astronomers can't establish its exact age because the core is in the process of crystallisation. A star loses its outer shell during its transformation into a white dwarf. Its mass decreases and when it runs out of fuel, the star may turn into a black hole. During the crystallisation process, the temperature drops due to a lack of additional energy sources. Astronomers speculate that such stars will eventually become black dwarfs with a diamond structure. The process is thought to take over 13.8 billion years, so it's likely that no such objects yet exist in the Universe. But this is the fate of almost all the stars in the Milky Way, including our Sun. (Read more.)
