Wow, this is really cool.  I wonder what the danger
is for one of these things acting like a diamond prism
and accidentally channeling a whole bunch of starlight
right across the galaxy killing off millions of
aliens in a blink of an eye.



Astronomers spy 10 billion trillion trillion-carat diamond

LOS ANGELES (AP) - If anyone's ever promised you the sun, the moon and 
the stars, tell 'em you'll settle for BPM 37093.

The heart of that burned-out star with the no-nonsense name is a 
sparkling diamond that weighs a staggering 10 billion trillion trillion 
carats. That's one followed by 34 zeros.

The hunk of celestial bling is an estimated 2,500 miles across, said 
Travis Metcalfe, of the Harvard-Smithsonian Center for Astrophysics.

"You would need a jeweler's loupe the size of the sun to grade this 
diamond," said Metcalfe, who led the team that discovered the gem.

The diamond is a massive chunk of crystallized carbon that lies about 
300 trillion miles from Earth, in the constellation Centaurus.

The galaxy's largest diamond is formally known as a white dwarf, or the 
hot core of a dead sun.

Astronomers have suspected for decades that white dwarfs crystallized, 
but only recently were able to verify the hypothesis.

A paper detailing the discovery has been submitted to The Astrophysical 
Journal Letters for publication.
