Eventually, the sun will cool off and become a giant crystal floating through space.

It's not a bizarre science fiction plot, but the takeaway of new scientific research published this week in the journal Nature.

You may have heard that billions of years down the road the sun will swell to a ravenous red giant star that will eventually swallow Earth.

But long after our planet has been ended, the sun will shrink to a cool white dwarf star and then slowly solidify into a massive white crystal, the study says.

That's a lot of bling wasted on the empty vacuum of space.

"All white dwarfs will crystallize at some point in their evolution, although more massive white dwarfs go through the process sooner," Pier-Emmanuel Tremblay from the University of Warwick's Department of Physics in the UK explained in a statement.
