I was watching a documentary on tv this morning on astrology, which was part of BBC2's Open University programs. At one point there was a mention of Stardust, and how we are all made of this. Interesting idea, if you think about it. "Every element on earth, except for the lightest, was created in the heart of some massive star. And the heaviest elements -- such as gold, lead and uranium -- were produced in a supernova explosion during the cataclysmic end of a huge star's life, says LSU physicist Edward Zganjar. 'Those elements were ejected into space by the force of the massive explosion, where they mixed with other matter and formed new stars, some with planets such as earth. That's why the earth is rich in these heavy elements. The iron in our blood and the calcium in our bones were all forged in such stars. We are made of stardust', Zganjar said."
