The Keck telescopes have taken astronomers to the most remote neighborhoods of our galaxy, peppered with mini-galaxies-within-a-galaxy that are sparsely populated with just handfuls of stars. Although these galaxies used to harbor supernovae that produced most of the elements in the periodic table, those factories were shuttered long ago. Keck uncovers the history of these ghost towns–and their defunct manufacturing economies–by discovering what the few surviving stars are made of.
