A Dying Star Turned Into a Giant Crystal Ball — And It's Older Than Our Solar System

[00:00:00]Somewhere in deep space, there's a dying star. And it's been hiding a secret for billions of years. Scientists discovered that as certain stars reach the end of their lives, they collapse inward and their core transforms into something almost impossible. A giant crystal ball thousands of miles wide, made of pure solidified oxygen and carbon. Not a metaphor, an actual cosmic crystal floating in the dark. These are called white dwarfs. and the oldest ones act like frozen clocks. Perfectly preserved time capsules from the earliest age of the universe. By studying how they cool and crystallize, astronomers can actually calculate how old the universe itself is. One ancient white dwarf recently revealed it had been slowly crystallizing for longer than our entire solar system has existed. That means right now, scattered across the galaxy, there are crystal stars older than the sun, just silently waiting to be found.
