Billions of years in the future, our dead sun will morph into a giant cosmic jewel, a new study suggests.

Like the vast majority of stars in our Milky Way galaxy, the sun will eventually collapse into a white dwarf, an exotic object about 200,000 times denser than Earth. To put that in perspective: A mere teaspoon of white-dwarf material would weigh about as much as an elephant, if you could somehow transport the stuff to our planet.

Half a century ago, theorists predicted that white dwarfs solidify into crystal over time — and the new research has found that this is indeed the case. [Death of a Sunlike Star: How It Will Destroy Earth (Infographic)]

"All white dwarfs will crystallize at some point in their evolution, although more massive white dwarfs go through the process sooner," study lead author Pier-Emmanuel Tremblay, a physicist at the University of Warwick in England, said in a statement.
