Astrophysics reports 'to impress your favorite lady this
Valentine's Day, get her the galaxy's largest diamond.' A newly
discovered cosmic diamond is a chunk of crystallized carbon 50
light-years from the Earth in the constellation Centaurus. It is
2,500 miles across and weighs 5 million trillion trillion
pounds, which translates to approximately 10 billion trillion
trillion carats, or a one followed by 34 zeros. A cheesy,
unrealistic simulation is also available. AP has a story as
well."
