The Distribution of H2CO in the Far Outer Galaxy

We propose to observe 9 giant molecular clouds in the Far Outer Galaxy (galactocentric distances >16 kpc) in the 4.83 GHz transition of H2CO. We have detected the 141 GHz line of H2CO in these ob jects and we want to use the Arecibo observations to constrain the density and abundance of this species in the very different molecular environment of the Outer Galaxy. In addition, the implications of determining the H2CO abundance for the new interdisciplinary field of astrobiology are discussed.
