Description
Carbon's unique chemical properties, its relatively-high cosmic abundance, and the well-established existence of many carbon compounds in extraterrestrial sources all argue for that element's substantial role in astrobiology. Recent high-profile projects have reported organics in such diverse environments as the Saturnian satellites (tholins with Cassini), comet tails (amines and glycine in Stardust samples), and about supernovae (PAH molecules found by Spitzer). Moreover, the terrestrial carbon inventory for both early and present-day terrestrial life has been altered by organic molecules from both meteorites and interplanetary dust particles and, perhaps, comets. This session will be an opportunity for a diverse group of contributors with interests in observational astronomy, laboratory analysis and simulations, theory, and future missions to share their latest results, all united with a common interest in the chemistry of carbon-containing molecules. Although the session's focus is on organics, certain inorganic materials, such as sulfates and ammonia, may also have influenced carbon chemistry and life's origin, and so relevant contributions related to those are welcome.
