DESCRIPTION:Understanding the origin of the elements is one of the major ch
 allenges of modern astrophysics. Ultraviolet (UV) spectroscopy of metal-poo
 r stars provides access to many absorption lines of elements and species th
 at are otherwise undetectable in optical or infrared spectra. I will show h
 ow UV spectra collected with the Hubble Space Telescope have expanded stell
 ar chemical inventories to more than 65 elements per star and identified si
 gnatures associated with r-process transuranic fission fragments. I will al
 so show how UV spectroscopy with the ANDES instrument on the Extremely Larg
 e Telescope and the proposed Habitable Worlds Observatory mission could rev
 olutionize our understanding of the first stars in the decades ahead. To ar
