WebFrom New Scientist, "Famed scientist P.W. Merrill fifty years ago observed the signature of live technetium - an element that has no stable isotopes - in the starlight from certain types of stars, thereby proving the then-controversial theory that stars make atoms via a process called nucleosynthesis." promethium. WebThis happens because the nuclear binding energy is at its maximum at iron. Hence lighter elements were made in ordinary stars, using fusion. However, heavier elements were made in supernovas, as huge amounts of extra energy are released during the explosion, some of which is used to force heavy nuclei together and create heavier elements.
