Space reports on a study published in the Astrophysical Journal on what could be the coldest white dwarf (relatively speaking), cold enough to have become a diamond the size of planet Earth.
When talking about stellar objects, "cold" is a relative term; this white dwarf is still burning at 4,892 degrees Fahrenheit (2,700 degrees Celsius), but that's 5,000 times cooler than the center of Earth's sun.
Such a cool object would be largely crystallized carbon, similar to a diamond, the scientists said. Astronomers have theorized that these objects should be lurking in the universe, but diamond stars are difficult to detect because they are so faint.
