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. |
