Planetary atmospheres may play an important role in the habitability of a world. To better understand the chemistry that occurs in the broad range of atmospheres that exist in the universe, we have run a series of laboratory atmosphere simulation experiments ranging from the cold nitrogen/methane atmospheres of Pluto and Titan to the warm carbon dioxide dominated atmospheres of Venus and some extrasolar planets. I will discuss what we have learned from these experiments and from exploration of the solar system.
Sarah Hörst is an Assistant Professor in the Department of Earth and Planetary Sciences at Johns Hopkins University where she studies the formation and composition of planetary atmospheric hazes.
