This is a pretty old discovery (2004, haha) but it is certainly one of my favorites. Basically, there is a GIANT DIAMOND FLOATING AROUND IN OUR GALAXY. How freaking cool is that?
Okay, well, here’s how it was formed: when a star burns out it becomes something that’s known as a white dwarf and at the core of this particular white dwarf is a very large (understatement of the century) diamond. It’s in the constellation Centarus, about 50 light years from us, and the Harvard-Smithsonian astrophysicists that discovered it lovingly named her Lucy (I’m particularly fond of this seeing as I’m a gigantic Beatles nut.)
Most scientists were pretty sure that star cores crystalized after death, but Lucy was their first confirmation of this theory. She weighs 10 billion-trillion-trillion-carats, far surpassing the previous record held by the Golden Jubilee at 546 carats.
The Golden Jubilee diamond at a laughable 546 carats
Now, since us earthlings usually believe that diamonds are rare and incredibly valuable, you might be shocked to know that Lucy is not the only giant diamond floating around out there. In fact, most (if not all) white dwarfs eventually crystalize into diamonds in the sky. Of course this takes a rather long amount of time (about 2 billion years after the initial death of the star) but I’d say it’s worth the wait.
