"Unprecedented Transformation: Star Becomes Cosmic Diamond"
Scientists have discovered a white dwarf star, HD 190412 C, located just 104 light-years away, that is slowly crystallising and turning into a "cosmic diamond". The process of crystallisation will take millions of years, and astronomers are studying the star to understand how the dead remains of certain stars harden into a dense core of crystallised carbon and oxygen. However, the process could take a quadrillion years, making it highly unlikely that astronomers will find one anytime soon.
