Valentine's Day Special - Space Diamonds
From the microscopic
Back when "nanotechnology" was still pure science fiction, "nanodiamonds" from outer space became science fact. First discovered in meteorites in 1989, these tiny diamonds average 3 nanometers across - 300,000 of them would fit side by side across the width of a human hair - and contain just a few thousand carbon atoms.
…to the astronomic
The 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.
