"White Dwarf Star Crystalizes into Giant Diamond in Nearby Galaxy"

Astronomers have discovered a white dwarf star about 104 lightyears from Earth that is slowly crystalizing into a diamond the size of a planet. The white dwarf is part of a quadruple-star system called HD 190412, and data suggests it could be around 4.2 billion years old. White dwarfs are the final state of about 97 percent of the Milky Way galaxy's stars, including the Sun, and will eventually become cold, dark, diamond-like objects called black dwarfs. The discovery of a star undergoing crystallization so close to our solar system will help astronomers better understand its course and how common such stars are.
