Life beyond Earth

Athena Coustenis is Director of Research at the French National Research Center (CNRS) and an astrophysicist at the Laboratoire d'Etudes Spatiales et d'Instrumentation en Astrophysique (LESIA) of Paris Observatory. She is Co-Investigator of three of the instruments (CIRS, HASI, DISR) aboard the Cassini/Huygens mission. Her expertise in space missions has allowed her to Chair and to contribute in several advisory groups within ESA and NASA. Dr Coustenis is currently President of the EGU Planetary Sciences Division and President of the International Association of Meteorology and Atmospheric Sciences, as well as Secretary of the Executive committee of the Division for Planetary Sciences. She is a member of several editorial boards and has been awarded several NASA and ESA achievement awards. She is also winner of the American Astonomical Society's 2014 Harold Masursky Award for outstanding service to planetary science and exploration. Thérèse Encrenaz is Senior Director of Research at CNRS and an astrophysicist at LESIA, Paris Observatory. She has been involved in many planetary space missions and has been a Mission Scientist of the European ISO (Infrared Space Observatory) mission. She has chaired the Science Advisory Committee of CNES for the exploration of the Universe. She is currently a member of the E-ELT Project Science Team and is also serving as Vice-President of the Scientific Council of the Region Ile de France. Dr Encrenaz is the author of more than 250 refereed articles, a few lecture books and a dozen of popular books. She has received several awards including the Silver Medal of CNRS and the David Bates Medal of the European Geophysical Union.

'A thorough tour of the possible abodes of life elsewhere in the cosmos, Life Beyond Earth unifies the study of planets in a way that should be more common but is still rare. Coustenis and Encrenaz provide a clear and engaging exposition of planetary habitability, giving an authoritative picture of the wealth of information that we have on planets and the engaging mysteries that remain unsolved.' Jonathan I. Lunine, Director, Center for Radiophysics and Space Research, Cornell University, and author of Earth: Evolution of a Habitable Planet
