Soccer Balls in Interstellar Space

Interstellar space is teeming with solid, minute particles called "dust", a large fraction of which are rich in carbon that was formed in the cores of solar-type stars. When dust grains are ejected into interstellar space from dying stars, they are catalysts for the formation of the next generation of stars. Therefore, an investigation into the amount and composition of the dust produced by dying stars as well as its subsequent return to interstellar space is a crucial step in understanding stellar evolution and the chemical evolution of galaxies.
