SUMMARY:Planets in a Bottle: The Role of Laboratory Experiments in the
  Search for Life\, Special Talk at WID Orchard Room \, Sarah Horst\, J
 ohns Hopkins University\, Sara Horst\, Johns Hopkins Unversity
DESCRIPTION:From exoplanets\, with their surprising lack of spectral f
 eatures\, to Titan and its characteristic haze layer\, numerous planet
 ary atmospheres may possess photochemically produced particles of "haz
 e".  With few exceptions\, we lack strong observational constraints (i
 n situ or remote sensing) on the size\, shape\, density\, and composit
 ion of these particles. Photochemical models\, which can generally exp
 lain the observed abundances of smaller\, gas phase molecules\, are no
 t well suited for investigations of much larger\, solid phase particle
 s. Laboratory investigations of haze formation in planetary atmosphere
 s therefore play a key role in improving our understanding of the form
 ation and composition of haze particles. I will discuss a series of ex
 periments aimed at improving our understanding of the physical and che
 mical properties of planetary atmospheric hazes for a wide range of ex
 oplanets including super-Earths\, and mini-Neptunes and how we hope to
  use our results to aid in the search for life.<br>
