Our Galaxy, the Milky Way, is surrounded by 152 groups of stars, which are called globular clusters. They appear to be the oldest things in the galaxy, the first thing to form, and hold valuable clues about how the first stars and galaxies formed.
When stars die, the materials the star has been fusing for millions of years, all the way up to iron, are melted back down into sub-atomic particles. Then they are remade in a process called explosive nucleosynthesis. More than remade, the elements higher than iron, up to uranium are assembled in a flash.
