The Galaxy's Largest Diamond

unassimilatible writes "The Harvard-Smithsonian Center for 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."

    As stars run out of hydrogen, they start fusing other elements present in their cores. This takes them through different stages of stellar evolution (red giant, horizontal branch stars, assymptotic branch stars, etc.) They continue to gain energy from this process until they reach iron. When these stars fuse elements heavier than iron, they don't actually get a net energy output from the reaction and thus their pressure source (fusion) cannot sustain the equilibrium against the gravitational force that constantly tries to collapse them. This is when a supernovae event occurs. As the star collapses under its own gravitation, the core rapidly fuses anything it can as the density increases. This is why the previous poster is right in saying that the main source for elements heavier than iron in the universe is supernovae.
