Oort Cloud comets, as well as TNOs 2005 FY9, Quaoar, and Pluto, are known to contain ethane. Even though this molecule is found in several outer solar system objects, relatively little information is available about its amorphous, metastable, and crystalline phases. In new experiments, we have prepared ethane ices at various temperatures, and heated and ion-irradiated these ices to study phase changes and ethane's radiation chemistry with near- and mid-IR spectroscopy. Recent results will be presented at this meeting. An improved understanding of solid-phase ethane may contribute to future searches for this and other hydrocarbons in the outer solar system. This work was conducted by LLR while a summer research intern at the Goddard Center for Astrobiology, Goddard Space Flight Center. Additional support from NASA's Outer Planets, Planetary Atmospheres, and Planetary Geology and Geophysics programs is acknowledged by all of the authors.
