By extrapolating what we know on the origins of life on Earth, and in particular on the chemical processes which gave rise to the first living system, Europa and Titan appear as two major targets for studies of exo/astrobiology in the outer solar system. With the likely presence of water oceans relatively close to its surface, coupled to possible sources of organics, the emergence and sustaining of life on Europa seems possible. On Titan, it cannot be ruled out. But the main exobiological… 

Enceladus: Cassini observations and implications for the search for life

Aims. The recent Cassini discovery of water vapor plumes ejected from the south pole of the Saturnian satellite, Enceladus, presents a unique window of opportunity for the detection of extant life in

Water and Volatiles in the Outer Solar System

Space exploration and ground-based observations have provided outstanding evidence of the diversity and the complexity of the outer solar system. This work presents our current understanding of the

Satellites of Planets in the Solar System

The existence of water on the satellites of the planets of the solar system is discussed. The Galilean satellites of Jupiter, especially Europa, are very promising candidates for hosting an ocean of

Energy Production and the Potential for Life on Outer Solar System Satellites

Scientists searching for extraterrestrial life forms have recently begun to focus their attention on a group of icy bodies in the outer solar system. These satellites, particularly Europa, Enceladus,

Solar System Magnetospheres

This article proposes a short review of our present knowledge of solar system magnetospheres, with the purpose of placing the study of Saturn’s magnetosphere in the context of a comparative approach.

Low-Temperature Alkaline pH Hydrolysis of Oxygen-Free Titan Tholins: Carbonates' Impact.

To produce reliable laboratory analogues of organic aerosols produced in Titan's atmosphere that play an important role in atmospheric and surface processes and in organic chemistry as it applies to exobiological interests, a device for the synthesis of clean tholins was developed and tested, and a list of potential precursors of these compounds was established.

Parachuting onto Another World: The European Space Agency’s Huygens Mission to Titan

On Friday, January 14, 2005, a group of nervous and excited scientists gathered in the control room of the European Space Operations Centre (ESOC) in Darmstadt, Germany, to attend an epochal event in

The Possible Emergence of Life and Differentiation of a Shallow Biosphere on Irradiated Icy Worlds: The Example of Europa

Iradiated ice-covered ocean worlds with rocky mafic mantles may provide the conditions needed to drive the emergence and maintenance of life, and in such chemostatic environments, fuels may eventually outweigh oxidants.

Europa: Prospects for an ocean and exobiological implications

As far as we know, Earth is the only planet in our solar system that supports life. It is natural, therefore, that our understanding of life as a planetary phenomenon is based upon Earth-like

Organic Chemistry and Exobiology on Titan

Exobiology is not only the study of the origin, distribution and evolution of life in the universe, but also of structures — including at the molecular level, and processes — including organic

Exobiological Implications of a Possible Ammonia–Water Ocean inside Titan

Models of Titan's thermal history indicate that an ocean consisting of an ammonia-water solution, as much as 200 km deep, is presently concealed beneath a crust of water ice. Conditions within this

Europa's Crust and Ocean: Origin, Composition, and the Prospects for Life

Abstract We have considered a wide array of scenarios for Europa's chemical evolution in an attempt to explain the presence of ice and hydrated materials on its surface and to understand the physical

Possible Degree of Evolution of Solar-System Microorganisms

The present work is concerned with the search for life in the outer Solar System. We devote our attention to the determination of the likely degree of evolution of such biota (Chela-Flores, 1996;

Oxirane: An Exotic Oxygenated Organic Compound on Titan?

After the discovery of CO, CO2, and more recently H2O in Titan's atmosphere, the chemistry of oxygenated organic compounds in this environment has been limited to theoretical studies only. Both
