Got Calcium?
Lithograph with Classroom Activity
 |
Where do the elements around us come from? Many are produced in
stars, and liberated when these stars explode. This lithograph features
a beautiful image of the remains of an exploded star, taken by NASA's
new Chandra X-ray Telescope. The back explains stars' roles as "mighty
chemical factories," and contains a classroom activity.
