We have found evidence that the presence of ‘carbon onions’ and other large molecules derived from fullerene could be commonplace in space. These are the most complex molecules detected so far and their discovery has important implications regarding our understanding of circumstellar and interstellar physics and chemisty, as well as of molecular processes in the final stages of stellar evolution. The work also provides new insights into understanding the origin and composition of the so-called diffuse interstellar bands (DIBs), one of the most enigmatic phenomena in astrophysics. Discovered
