Where do Atoms Come From
by Alan Stahler

Everything around us is made of atoms - atoms are the building blocks of the universe. But there was a time, back when the universe was young, when these atoms did not exist. The atoms in the Earth, the atoms in our bodies, had to be assembled. The atoms of which we, and everything around us, are made, were assembled in stars - stars like our sun ... like Betelgeuse, the orangey star in Orion.

The sun and Betelgeuse are very different stars, and they assemble different types of atoms. Our sun can make helium, but it cannot make oxygen, or iron; Betelgeuse can .. but it cannot make silver or gold ... until it explodes.

At the next meeting of Nevada County Astronomers, Al Stahler will describe how we can see the building blocks of the universe ... being built.
