ICEE: Next Generation Exobiology and Astrobiology StudiesThe presence of organic molecules, from simple to complex form are found in the ISM (interstellar medium). Perhaps the largest of these molecules are the PAHs, or polycyclic aromatic hydrocarbons, while smaller versions of PAHs have been identified in meteorites, IDPs (interplanetary dust particles) and comets within the Solar System. Life is comprised of organic molecules and, in one sense; the search for life is the search for and identification of organic molecules. This yields an interesting question. Can the organics in the ISM serve as the chemical feedstock to the prebiotic molecules identified in meteorites, comets and IDPs in a “Top-Down” synthesis mechanism? Most studies
regarding the formation of prebiotic molecules focus on a “Bottoms-Up” mechanism, whereby simple organic compounds in ice form larger, more biologically relevant molecules when exposed to UV irradiation. Here we present a next generation experimental setup which focuses on if larger, interstellar organics, such as PAHs (polycyclic aromatic hydrocarbons) can serve as the chemical feedstock for the organic inventory found in the Solar System.
