Nucleosynthesis is the process that creates new atomic nuclei from ... With the
formation of stars, heavier nuclei were created from hydrogen and helium by
stellar ... Elements heavier than iron may...
Atoms that are heavier than hydrogen were made by nuclear fusion after the big
bang. Initially, only the lightest element, hydrogen, was present.
Dec 2, 2010 ... Just what do astronomers mean when they say we're all made of star stuff ... All
except atoms of hydrogen and one or two of the next lightest elements. They
were formed even earlier, shortly after the Big Bang began 13.7 billion years ago.
