Astronomers have identified possibly the coldest, faintest white dwarf star ever detected. This ancient stellar remnant is so cool that its carbon has crystallized, forming -- in effect -- an Earth-size diamond in space. The object in this new study is likely the same age as the Milky Way, approximately 11 billion years old.
