It was not the supernova that produced the heavy elements. The supernova scattered the elements produced in the red giant star as
the star collapsed in on itself and exploded. Our sun is producing heavy elements in its core as we speak. Being a second generation
star, however, the process may not have advanced to very far at this stage.

I hope this helps.

Very good answer Donal, but other are out to find out the truth.
Sagan said "we are all made of star stuff". What he meant by that was
that the chemical elements of which we and everything on Earth are
made, originated in the huge explosions which take place at the end of
a star's life. This explosion is called a supernova, and if it were not
for these explosions, none of the chemical elements heavier than Helium
would exist. There would be, for example, no oxygen or iron, two
elements which are essential to life on earth as we know it... and
steel sailboats.

Don't you find it strange that a little supernova is able to produce all
these elements? After all, the great big grandaddy of all explosions, the
Big Bang, managed to produce only two elements!!!!




I use my telescope to :
1) to learn how our Sun will evolve as it grows older

Bull****!
What's gonna happen to our Sun?


2) to learn how our galaxy will evolve

How will it evolve?

3) to learn how the universe will evolve

It'll get bigger, huh? Perhaps you would tell us about your observations
and the conclusions that you have drawn.



Really Joe, I think that you overestimate your ability to interpret what
your instruments tell you. I bet that you have learned nothing at all
about the universe from your telescope. You could easily prove me wrong by
posting something that we haven't already read on the Intrernet - but I bet
that you can't!
