Research CPS Research themes: Astrobiology, Magnetospheres, Exoplanets, Planet Interiors and Surfaces. Astrobiology Astrobiology is a deeply interdisciplinary field investigating the possibility of life beyond the Earth. Magnetospheres Planets with magnetic fields are surrounded by regions known as magnetospheres. CPS members study these, and charged particles trapped within them, using spacecraft instruments and computer models. Exoplanets Spectroscopy of exoplanet atmospheres, including data reduction, atmospheric modelling, novel retrieval techniques and space missions. Interiors Space missions have revealed our solar system displays a rich variety of bodies with a diverse evolutionary history. Surfaces Planetary surfaces record geological events which are a combination of internally and externally driven phenomena. Missions Our research has contributed to space missions.
