Exhibition Text

The material of stars is recycled over billions of years. Interstellar gas clouds collapse to make stars. Stars forge heavy elements and return their gas to space. This material enriches gas clouds from which new stars are formed, and the cycle continues. Each generation of stars is made in part from the ashes of previous generations.
