Abstract :
Stars seem
permanent, but they are not. When stars collide, collapse, or explode
astronomers leap
into action to study the shreds of destruction. The death of stars
creates new
chemical elements and blasts them into the galaxy to become the stuff
of new stars,
planets, and, perhaps, living things.
he oxygen atoms
in the air we breathe, the calcium in our bones, and the iron in our
blood were
created when stars were destroyed 5 billion years ago.
