Press Release: Titan's Atmosphere Comes from Ammonia, Huygens Data Say

The University of Arizona news site has a press release regarding evidence that the nitrogen in Titan's derived from the breakup of ammonia, possibly pumped into the atmosphere by cryovolcanism. The releases cites the relative lack of non-radiogenic Argon, which has a similar volatility to nitrogen and should be present in a percentage akin to the solar nebula, as compared to nitrogen if the Nitrogen came from molecular nitrogen locked in accreted ices. In addition, the enhancement of radiogenic Argon and the discovery of possible cryovolcanism by RADAR and Huygens DISR further implies that ammonia has been released from the interior.
