SUMMARY:The cosmic journey of the elements\, from dust to life\, Astro
 nomy Colloquium\, Lia Corrales\, University of Michigan
DESCRIPTION:To understand our origins\, we must understand the role th
 at interstellar dust plays in delivering heavy elements to planetary s
 ystems. This requires an understanding of the chemical composition\, s
 izes and shapes of interstellar dust: astromineralogy. X-ray observati
 ons provide the most direct means for astromineralogy through the abso
 rption signatures of dust imprinted in the spectra of bright Galactic 
 X-ray sources. I’ll review the latest results in astromineralogy and
  our work on connecting interstellar dust with suspected extra-solar g
 rains collected in our own Solar System. I’ll also describe how the 
 recently launched XRISM space mission is poised for major breakthrough
 s in astromineralogy. Finally\, I’ll show how I am adapting this wor
 k to study aerosols in exoplanet atmospheres\, which have the power to
  alter planetary climate and habitability. By investigating exoplanet 
 transits at short wavelengths\, we are opening new windows on aerosols
 \, atmospheric escape\, and the role that stars play in sculpting plan
 ets.
