SUMMARY:Life in the Light: Photochemical Insights Towards Life as a Pl
 anetary Phenomenon\, Public Research Seminar\, Dr. Sukrit Ranjan\, Nor
 thwestern University
DESCRIPTION:Advances in origins-of-life chemistry are transforming our
  understanding of how life emerged on Earth\, while upcoming space mis
 sions and telescopes offer the prospect of detecting life on other wor
 lds. Fundamental to both quests is interaction of UV radiation with mo
 lecular systems (photochemistry). Photochemistry controls the chemical
  context for the origin of life on Earth and influences the molecular 
 signposts with which we hope to detect life elsewhere. I will share ph
 otochemical work which refines our understanding of early Earth enviro
 nments\, and demonstrate how such understanding enables assessment and
  improvement of theories of origins-of-life chemistry. I will discuss 
 photochemical efforts to elucidate potential atmospheric biosignatures
  of life on other worlds\, and show how the search for life on other w
 orlds may enable tests of theories of the origin of life. In sum\, I w
 ill review theoretical\, experimental\, and observational work towards
  understanding the origin and distribution of life in the universe thr
 ough the lens of photochemistry.<br>
