Moby had it right: we are all made of stars. Astronomers have long known that stars fuse hydrogen and helium, ultimately creating somewhat heavier elements, which are then expelled through the universe when stars explode as supernovae. All the carbon and calcium in our bodies, all the oxygen we breathe, originated in stars.
But where is the cosmic factory that manufactures the heavier elements—say, gold?
Now a Cal computational astrophysicist may have helped solve that mystery.
